i like the panel effect thingy on the very left side of the sig
overall i think it's too bright/washed out/over-exposed. Also don't like the green tint on the render's skin. Text would be alright without the 'bubba' (which is way too small. It looks squished and is just too small to put text effects on it, specifically that type of reflected gradient you used).
I think you need to get away from this monotonous, washed out type of style before u worry about text.
