*Laugh!!!*
You are quite a fan of violence.
But... yes, smoke would've been neat...
I like how you made the blood sparkly. Though the term "sparkly" might contrast a little with the general intent of the image...
What exactly is the incapable wing-like bit on the creature's back for? I've always wondered... assumed that maybe they had wings and then something happened to 'em.
Now I think I might point out some suggestions...
Perhaps this might go with Dragyn's statement, almost...
But the front of the shirt forms to his body in a bit of an odd way... first it's kinda tight, then expands too much at the shreds.
In one spot it looks like you made a shadow for the blood, over his leg. I'd make it more subtle, personally... it almost looks like more blood and makes the stream of droplets appear too consistent.
The background is better... but I'm not sure if it goes with the image all that agreeably. Close, but a little too... cheery... ya' know?
May just be my opinion, that...
Usually I'd say that what the armored individual is doing is altogether highly unlikely to be possible, and the length of that sword would be very inconvenient to its holder, at their height. However, in many fictional situations, the bigger the better, and impossibilities are, of course, regularities.
*Shrugs* Your call, there.
I know that looks like a lot of text, but it really wasn't that much when I was just thinking it...
Really, it's only 3 suggestions and one side-note! >.<
