Ok after downloading, testing and looking to it - lets rate it:
The main point is for me: I know this icon must have a dark touch, but somehow it's to dark, even ingame. For example look at the DIS icons, the eyes are nearly gone, also the passive item is with eyes can be better.
How I think you can improve it:
You can color the eyes a little bit in green. Also you can add at the side of the eyes something green like in this icon:
But at you icon make the dreen some darker. After that I think it's a perfect "CrippleFear" Icon.
Ok lets get in points:
+ You got both, normal and passive, icons
+ Works ingame
+ You look at it and know what is it about
+ The hand look very good with the blood effect
- As I said, it gets to dark at the end. so this maybe need an improve.
All in all my rating would now 4,5/5 - If this isn't to dark at the end, I will give 5/5 - because then it's perfect for me.
