This has some potential but it's really flat. You're also kinda over-contrasting. The main thing it's lacking is wow-factor though. It's mainly due to the somewhat washed colors and lack of decent lighting transition.
make the side on the left with more contrast! or make it redder, that could help with the transition..even though i know it's meant to be dark to light
i'll just quote sky and say "rule of thirds.." well add a more defined lightsource and work on the bg on the left if not scratch it, it looks lq/oversharpened and thus flat. so like my bro said, give it some depth or maybe do some smudging on the left.
I disagree with this. This signature has some kind of "good and evil side"-effect, and the render is perfectly fitting in the middle of it. Some text at the intersection points would be cool though.
that depends if the render, or the sides are the focus. if you look at it now, the first thing that pops up are the two c4ds in the bg, oth leading towards/positioned at a focal point.
