Frankly, I don't think I have so much talent neither, when I started at highschool I had the worst grades and everyone around me was painting better and drawing more smoothly.

I said to my self that if my cards aren't talent, then my cards will be hardwork and here we are now... I do it professionally and earn money from it.

You never know :) talent with out practice is more horrible then no talent at all (which doesn't even exist in my opinion).

If you like to paint, draw or any another activity, just do it until you will be sick of loving it :D Wish you the best!
