Hello. This is my first paragraph.

I decided to learn eEnglish.

The names of languages are proper nouns and should be capitalised.

[I working to night and ı do every moon exercyse.]?

I'm not entirely certain about what you meant to convey with this sentence. Perhaps you can provide the native text?

My eEnglish is a little poor.,

You can merge this sentence with the one below. I have changed the period into a comma to allow for this.

Sso everyoneI'd like to say sorry andto everyone and thank you.

I rephrased the sentence so that it sounds more fluent.
