On the Vagrant Story mockup, I see that you have a great technique, since both sprites, hero and skeletons, are very well-done. BUT... Something I noticed is that the skeletons sprites and the hero sprite seem to be from differente games, since they do not share the same spriting style. For an example, it looks like the enemies comes from a Square-related RPG, like FFVI, and the hero comes from something inside Fire Emblem style.
