Quality in-game is decent, but it could be a lot better. I like the originality and that it's at least transparent.
Try to improve the in-game quality. Since you made this in Gmod you should be able to render out a higher quality image from your computer.
It's kind of a boring image to look at, and I could see you improving it by adding some kind of effect to it such as a couple of different colored shapes behind him, or some text saying something like "bon appetit" or "bone app the teeth" if you're real memey.
