It's supposed to be with this type of signature. It's called a "sprite tag", which requires small, sprite, renders. I like it, but the text drags to the focus away from the render so you might want to make the text simpler.
like the text, think the rest of the sig needs to come up to par with it. not saying rest is bad but font sticks out alot. if colors in sig came out more vibrant it would look better imo.
I'd have to agree with everyone else, the text is a bit more of a focal point than the actual sprite, but good job, i like it
