For the killer priest guy, his hand seems to lack form. It kind of flattens as it goes into his coat. The mask guy is a very nice line drawing, but I have a couple problems with it. His left foot looks to be anatomically off, and his right looks like it's further behind than the left even though it should be closer to the viewer.
I think the ear should be lower on the goblin-head drawing. They usually start around the base of the nose I think.
