I don't like the size that you've used, it's too big in my opinion. Also the render could blend in better with the background, and the colours (Pink) don't fit at all.
yeah, i got a smaller sized one i know, the render isn't blending in anyways, the pink would explain the text: too epic for my shirt thx for c&c
One question, is that supposed as a signature? Because then it would be really big. Anyways the render looks really choppy.
