Introducing myself

I'm here to practice my English (languages are always capitalized)
Help me to improve my English plz!

("plz" is Internet/text slang for "please", but try not to use slang while learning a new language - it can be distracting)

FYI: I like your profile picture. Women are beautiful enough without makeup.

Introducing myself:

myself is a pronoun, and you're not improving yourself, you are improving the indirect object, which is your English.
