Should i keep drawing?

NO!
don't you DARE stop drawing.

if you love something, don`t stop doing it just because someone says something about it you don`t want to hear.
the fact is: some people ask for opinions on their work, and they will get EXACTLY what the other person is thinking about it.

the more you draw and practise, the better you will become and develop your own style.
encouragement is one thing, but critism is tied in with it as well. some times it`s nice to know what`s going to work and what isn`t. after you almost finish a picture, take a break and stand back and look at it to see what you can ajust, change, colour, and touch-up.

NEVER stop drawing if you love it.
