Hmmm, I guess you're right... I'll try to do some fixing before the deadline. 

styles are classing here. why do the two monsters have dark outlines, while the people lack all outlines? I like the knight and the horse, it'd be nice if the rest matched its rendering. The girl looks good too, the random single pixels on her dress just read as noise, hinting at a few swooping folds would look nicer imo. the monsters are what's really bringing the piece down though, i'd advise getting rid of their outlines and adding more detail (maybe some texturing?)
