heres another sig i made.
okay buddy, let me give you some CnC on this.
First off....the lines of the focal are "sharp" and the background is "smooth" so they don't really fit, understand?
you need to pull texture from the focal and use in the background.
Also, being a black and white image, it'd be best to stick with a black and white background.
That image is very hard to work with, I tried a crack at it and it was going to take me way too long.
the text is incredibly hard to read and doesn't really flow with image.
Usually the focal should be the....focal....not the text. the text should be an "accent" that's why we usually make it smaller and beside the focal, in order to not draw a lot of attention to it.
from what It seems like, you are taking a premade background maybe just changing the color. I'd like to see you be more creative and make your own. I don't have any tutorials for PS, but I'm sure one of the other designers do! for now please make some more images so I can get a better Idea of where you are with your talents.
try these renders and stocks out. Let's see what you come up with!
this one gives a real good opportunity to place lighting in your signature
