You've been 5$ed! I DON'T like this theme, though. It's a little done. The boy's illustration is really cool, but the emu could use some more detail (if you've going for little "v"s as texture, you've got put A LOT of them on the bird). I like your hand writing, though.
Another note with T designs, make sure you take advantage of the canvas that is the T-shirt. You've got a lot of empty space that's crying for more detail!
Please keep it up! I'll be posting my designs here shortly/hopefully.
