If you just want a basic sig, then you are right. But if he wants to express artistic abilities, which is what the Gallery is generally for, then it does, or needs to show some other sort of style. On topic: Try to save as a different file type, or if you compressed it to obtain a filesize, don't compress it as much, as alot of quality has been lost. Edit: As a basic sig I'll give it a 7/10 because I like the idea. For artistic abilities, I'll give it a 3/10.
