Nice style
It seems like you were heavily influenced by spawn or 'the darkness' comics around that era. Cause your style is very close to Capullo's. If I'm wrong I'm wrong but hey, you even named him Hell's Hitman XD
I know I seem mean only giving yah a seven but while this is really well rendered (all that fancy shading and stuff) the actual pose and silhouette is quite stiff, this is partly because of the wrong proportions on the main figure but I noticed he also has stiff and un-articulated hands. This tells me that the under-drawing is not so solid as all that flashy stuff would make it appear at first.
This is great presentation but if you stare at the drawing longer than a second it falls apart, is what I am getting at. Try to make yours longer lasting. This is GREAT stuff, rendering wise, but its very poor artistry at the foundational level. Merge the two together and keep drawing!
