I didn't study English today, but I did cleaned my house today. I didn't study English today, but I did clean my house.

Not putting "today" after "English" seems like you have never studied English (although we all get the point). Saying "did" emphasized the fact that while you didn't do one thing, you did do another thing.

I didn't study English, but I did cleaned my house today. I didn't study English, but I did clean my house today.

In order to make the sentence flow better it sounds more natural to say I didnt study english but I did clean today.

Additionally, II also need to complete my art by this weekend, so I wi'll draw a little more as well. I also need to complete my art by this weekend, so I'll draw a little more as well.

1. It's awkward to have multiple commas in such a short sentence. 2. Using "also" instead of "additionally" sounds a bit more natural. 3. In formal writing, saying "I will" is perfect. However, nobody says "I will" in speech. We almost always contract it into "I'll."

Additionally, I need to complete my artdrawing by this weekend, so I will drawwork on it a little more as well. Additionally, I need to complete my drawing by this weekend, so I will work on it a little more as well.

Again its just clarifying that youre talking about a specfic type of art.

See you tomorrow, all! See you tomorrow, all!

It's more conversational (and Southern, which I am) to say "See y'all tomorrow!" If you don't want to sound like you're from the South, you could say "See you all tomorrow" or "I'll see all of you tomorrow"

See you all tomorrow, all! See you all tomorrow!

See you tomorrow, all! See you tomorrow, all!

"See you all tomorrow!" is more natural, unless you intentionally say it this way to be playful.

See all you tomorrow, all!. See all you tomorrow.

Its better to put it in the beginning to clarify that youre speaking to mutiple people when you put you.
