Very nice but needs patching up. Like iHn said, you should up the contrast. If ur using a filter layer/gradient map you should erase it where the render is and softly around the edges of it. That should help.
You did a better job with the lighting in v2. Your text is pretty good. The blending is nice but try not to fade it too much. I don't know about this but the bg seems a little plain. Make the bg your main priority if you plan to make another version.
Its does look like it is a bit faded, but that is the only thing you really need to worry about in this sig. I would say that you should get more depth from this sig, but I think I like it more without it then with it. Nice sig man
