First time IWhen I first arrived in Armenia, I was very excited about the food, culture, and nature.

Armenians are dignified people who are also proud of their heritage.

'Also' sounds a bit strange to me here. Also is usually used to combine two distinct ideas, but being dignified and proud of one's heritage are pretty similar.

The capital city, Yerevan, is located arboundt 800 meters above sea level.

'Around' is correct here, but 'about' sounds slighly more natural to my native ear.

After a while, even the eye gets foggclouded with thait.

The national food is delicious, especially meat dishes like shashlik., which consists of

Shashlik is meat marinated beforehand and then grilled on skewers or a grill grid.

I would stylistically combine these two sentences.

And I fell in love with their bakeryd goods.

'Bakery' usually refers to the business where baked products are made, or the section in a grocery store where such products are sold.

TheyArmenians cook numerous Middle Eastern desserts like baklava and halva, which I adore, but their original ones are equally delicious.

Just a stylistic change.

FThe first time I arrived in Armenia, I was very excited about the food, culture, and nature.

You need the definite article "the" at the start of this sentence for grammatic correctness. "The" defines the meaning of a noun as one particular thing. It's an article (of speech) that gives a noun a definite meaning: a definite article.

The capital city, Yerevan, is located aroundsits about 800 meters above sea level.

The city is mostly consists of old buildings, layered with Martian-colored stuff.

I'd advise you to reconsider the color reference you chose here. It's too ambiguous, or unclear. Does "Martian-colored" mean the American UFO stereotype of "little green men"? Or does "Martian-colored" mean the color of Mars, known in English as "the red planet".

Additionally, the word "stuff" is also very ambiguous and unclear. It could literally mean anything. Was it paint, plaster, stucco, some type of vegetation, mold and mildew from disrepair? You leave the reader with unanswered questions, when you are attempting to educate and inform them about something you saw first hand. If your goal is to paint a mental picture of the Armenian capitol, you need to use clear and specific adjectives. Adjectives are words that describe nouns. Nouns are persons, places, things, or ideas. "Stuff" is also completely casual speech. If that isn't the tone you wish to convey, this is another reason to change it.

An "unknown substance" would elevate "stuff", if you really don't know what it was that covered everything.

After a while, even the eye gets fogged with thats become clouded with the [insert the specific substance you are referencing here] that fills the air, as well as the buildings.

You must specify what this "Martian-colored stuff" is. Your writing here is too confusing. The original sentence was awkward and also without needed detail. Such as, how is "stuff" on the building getting into everyone's eyes? You have to explain that. My guess is that the "stuff" is airborne, an not permanently affixed to the building. If not, you should say what is happening to cause the transference.

The national foodcuisine is delicious, especially meat dishes like shashlik.

When referencing both the overall national eating customs, as well as a particular dish in the same sentence, I would say using just "food" is too general here.

Shashlik is meat marinated beforehand and then grilled on skewers or a grill grid.

Using "marinated" and "beforehand" is a bit redundant and makes your sentence a little less smooth and flowing. Perhaps you could also add what kind of meat is used in this dish (i.e. beef, lamb, pork, poultry).

And I I also fell in love with their capitol city's bakery.

Specify who's bakery. Avoid starting sentences with "and".

They cook numerous Middle Eastern desserts like baklava and halva, which I adore, but their original one. However, Romania's national desserts are equally delicious.

You can break this sentence into two and make it less clunky.

They have gata, a sweet closed cakeake filled with honey and nuts inside.

You would not describe and cake as "closed" in English. What this sounds like is a filled cake; a cake with a filling of sweet and complementary substance(s) stuffed or baked inside.

I’ll definitely travel thereo Yerevan, Romania again, in the future.

Specify where you were, would like to go again, and recommend to others, as you only mentioned it at the beginning to the paragraph.

First timeWhen I arrived in Armenia, I was very excit for the first time, I was excited/amazed about the food, culture, and nature.

You can also say, I was in awe of the food, culture, and nature.

I suggested some synonyms to help you write better since there are many ways to say that you're excited.

The national food is delicious, especially meat dishes like shashlik.

What's the national food besides shashlik, if there's any?

It’s quite popular in Russia and the Caucasus region.

AndMoreover, I fell in love with their bakeryies.

I'm assuming that Armenia has multiple bakeries. If you remember, which bakery was your favorite one and why?

They cook numerous Middle Eastern desserts like baklava and halva, which I adore, but their original onecounterparts are equally delicious.

I edited a word to distinguish the ones from Armenia and the Middle East.
