Render seems a bit oversharpened imo.
Contrast of the totally sig seems pretty cool, don't really like the right stroke!
Depth is ok, but i don't really feel the splatter brushes u used... Don't like them at the places at the render. (like at her right arm)
Lightning is ok, but seems a bit overdone!
Flow could be worked on.
Blend the edges of the render though.
Anywayz, pretty nice sig!
Rate would be: 7/10 or something
U can improve a few things!
