If you're talking about the avatar pic you are currently using, the problem is...it doesn't help define your content in any way.
I don't see how it brands your work. Your name is "InnocentComputerGuy" but where in the logo doesn't it relate to the name/what you do?
The logo is missing the most important factor in logo creation....branding. If I saw a picture of this logo next to your username, I'd have no idea whether the logo is part of you, or someone else's company.
Also, just nit picking, but what is the dark spot in the upper left supposed to be?
It's cool graphic work, just to me, doesn't suit well as a logo.
