Some Sigs

its been a few years since ive done PS i kinda suck so if you can help me on what to improve that would be bad ass

 

All look great. The first one is the best. 3rd one needs sharpen, so is the 4th.

 

thanks for the info ill fix those

 

Now I really like the second.

 

I would not say that they look great.
You kinda took the same text at all those
signatures, vary your style man, try out new things.

Work on your flow and on your depth.
The lighting is really going random through every picture, blur the background, do not over sharpen the renders, doh.
