Zombie. Again. Oh noes.

Um yeah, I was following a tutorial for this. My first sig with more than 25 layers

 

It looks okay, just the color scheme is out of wack, the teal color there should go more with the redish in his face would look great gf though, also make the text a little brighter grey

 

The render is way to big for this, either make that smaller or your canvas bigger. Cut the scanlines, or atleast lower the opacity alot on them. Not liking the text, seems boring and too close together. Try going with something simple and not really extreme. I dont like the cyan color you threw in, its real random and doesnt fit the signature at all. I cant say much about the background, because its hidden, but all it looks like you did was added the clouds effect in there and maybe smudged it around a bit. I dont see any lighting effects added at all, just looks like its all over the place. Also, not sure if its just me, but everything looks really choppy.

 

why is the lighting coming from the left? when the on the render it shows the lighting coming from the right. Make sure you pay attention to this.

 

too big render on my opinion.. and I don't like the coulours, and the text doesn't fit to the sig :S
