yea i was wondering how i could fix this sig so the zombie looks less blue any suggestions

Well, if you have the .psd file, and that zombie is a seperate layer, you can always adjust the hue/saturation by pressing CTRL+U. I would suggest maybe take some saturation out of it, or change the color a bit.

set it to lumonsity if its on overlay,which it kinda look like cause its so into the backround,so set the render layer to lumonsity,also add a border,if u dont know how to then here

Open Up sig
Ctrl+A
Edit->Stroke
2 px. White
Blend mode-Soft Light
Blending Options-Bevel And Emboss-Chisel Hard-Size 0-
Stroke-Size-1px-color-black

and then the text read up on sum tuts,no1 like texts,i hate,almost evry1 hates it,but read up on sum blending tuts,and keep working around,and ll b good
