advices for the screenshots; stick the four images together, crop it so there's not too much grey, and you're done. you must not blurry the edges like you did, it's annoying for the viewer, and its easier to look at something solid. Also, take your screenshots with Warcraft 3 viewer 2 ( in the tools section ).
Same thing for your malfurion, not major changes, you just recolored with your pencil, try some creativity, so it can stand out more.
