This is terrible.
First of all, what's with the random lines on his skin?
Second why is his head almost as big as his body?
Third, the "pattern" on his clothing is too geometrical, and very lazily done I might add. Okay, maybe not lazily, but it looks amateurish.
Fourth, your "signature" was placed onto the picture after you scanned it on your computer.
Fifth, given how tiny this picture is, I'm willing to bet you copied this off of Google images, and is more likely not yours.
You're a terrible artist, and a possible thief.
Edit: Actually, you are a terrible thief. As I thought, I found the original online here, without your "signature." You, sir, are banned from MKO for plagiarism.
