It's been a while, hasn't it? >: Is this supposed to be abstract? <_> I can't seem to make out the stock. Either way it's looking relatively spiffy so far. Not too sure of the great mass of blackness at the left, couldn't you start making it fade a little earlier?
If this was an abstract piece, it's great. But since I see one of the ninja turtles there, it's not -_- Hiatus does this to you. It's good with colors and flow. I like the c4d dissolving through in this. But the render needs more size and more focal.
