Hey!
I think I'm a good choice for the job, because I'm playing with Dota 2, and I know all the heroes in the game.
I have a gamer past, I played with World of Warcraft for 6 years, and started Dota 2 5 months ago.
I'd like to think I'm good in drawing, You can check my (not full) portfolio, and I can show You some of my drawings.
I would make this T-shirt wiht PhotoShop cs6, with all my knowledge. I can try to design some new stuff for You (hand-drawing, then colouring in PS) or use the basic Pudge model, it depends on You.
I hope You'll choose me. I know I'm only a starter, but I promise I'll do my best.
Please contact me if You're intrested.
