Looks pretty cool from what I can see, though you should have more pics so we can really judge your work. The pose works imo, the finish around the scythe blade could be better, and I get he's not trying to kill the SM with it, after all if you can lift him up one handed over a small cliff by the head, do you really need the scythe?
If I could see more of the work I'd likely give this a better score, you should take a few pics from different angles and make a single pic with them all. I think that's a part of the reason why people are voting so low. I give a 7 because I like the pose and from what I can see most of the GS work is pretty good.
Does he kinda remind anyone else of a Krogan from Mass Effect?
