My only criticism is that the skins aren't that well defined. The chainmail and facial features seem blurred and fuzzy on some of them (in fact, the chainmail in general needs to look much more realistic; so far it just seems like grey crosshatching). And some of the skins are a little too bright (eg. Templar Knights). Maybe some one-pixel black outlines would help to define the different parts of clothing etc. a little more clearly? Otherwise, very nice.
