I hate saying so, but you're still in the slump. The lighting seems to have NO effect on the render. Dodge Tool areas near it and burn tools far from it. Add dark negative space to the bottom left hand corner. It could use some more colored pentooling, particularly a shade of blue. Add a gradient onto the render so it blends with the background. D:
It looks cool! It seems to need a little more lighting and thats all it needs. Still id give it a 10/10!
