Lets make this easy.
I'll post all my new signatures into this little topic, instead of spamming this section with topics named "New Sig" and such. Well, anyways, here are a new one I made, and my newest signature is a new one as well.
I could've made this one alot better, now that I look at it, and there may be a new version to it soon.
EDIT: This one is alot better. I actually like this one alot.
Alot of people make the same comment as you, saying that the render isn't really blended into the background. I kinda like it better when brushes aren't covering the render, because than whats the point of really having the full render?
