Shading- It's great, and I'm jealous. Goes to show a little time and effort goes a long ways.
Bloody hell- I think you did a rather good job with this, really good blood effects. though I did notice it bleed onto other things (I.E- the front arm, you can see a little red on the gauntlet.)
Finger- The finger is crooked, it's almost like someone chewed it.
The gauntlet(?)- The hand facing the viewer, with the gauntlet(I guess?) the squares on it are wobbly.
The leg in the back- It looks weird, the back leg looks a lot shorter than the one in the front. unless that is a bent foot, but its still weird looking.
