Wow, you took the time to transfer it into a shirt and taka pic? well, I have to give you the credit for that. It’s not that big to catch the detail, but I think you got the skills to do it better. Try scaning your drawing and maybe trace it in Adobe Illustrator, or you can use Adobe Photoshop and spruce it up a bit. http://www.designbyhumans.com/win/submit here you can find the DBH T-shirt design guide, it will help you with some templates and cool tips to make your submissions more appealing to voter. Best of luck, dude. Cheers!
