Set your heart ablaze
Hii !! Here is my first post on artfol ^^
This is a piece I did a year ago and it's one of my favourites, I had so much fun doing it...
Anyway I can see now some things that could have made the drawing so much better...

Feel free to give your opinion on this one, and things you think could be improved, color, composition, values...
I would be so happy to read your comments
