So Gleb wanted me to make him a sig so I did it how I know.
Unfortunately I just found out the maximum sig size is 450x100 so I'll just post it here for rating and comments.

It's okay.

But could be a lot better.
You've put the brush in good use for the background,
but you need to learn quite a lot about flow ;)

Follow some more tutorials and I'm sure you'll improve :B
Be careful not to COPY the tutorials though :P

I'm going to go off of what Alphasonik established
The concept is good but the execution could use a little work.
The text is a little awkwardly placed and the signature on the left or w/e is unnecessary
other than that just try to get the render to flow better with the background that you create you have potential.

Well the text had to be there or somewhere in the sig. I prefer it there.
The render is a bit off because I used extract tool but meh.
And it's not that I cant make the render flow with the background. I wanted it to stand out.
If you would look in my shop at examples for sigs you would see my other works have good flow. (And some weird text xD)
