Just a few that I made recently.

The first and third ones are the best and the others need some work.

Is it just me, or do they all seem to have a kind of low quality grainy look to them?
The first one, the twirly bit you have going around the gun looks really out of place. If you want to keep it, I'd blend it in more, it feels very stuck on over top of everything else.

Overall, your designs don't feel very unified. Your last one being the best example of it. From left to right it's C4d, stock, negative space with text. Nothing really goes together or compliments anything else. While each individual element looks good, they just don't fit together. Work on creating a piece as a whole, rather than dividing it into separate sections, and I promise you'll have better results.

I'll admit that i did stick the swirl over everything in the first one.
The second wasn't actually a render it was a stock, but of a drawing so I worked with what I had.
As for the last one I did for get a lot about shading and lighting but most of it is just a gradient, brushes, and the render, along with the lit end and smoke.
Im just getting back to gfxing so I don't expect everything to be perfect but I do enjoy the comments and help ^-^
Do they look grainy I can't really tell, I have had a lot of issues like that because it's hard to work having only one eye that can see anything.
Any advise and help is much appreciated.

Oh, and when I said last one, I said that thinking your current sig was a part of your post. My mistake.
