I like the 1st one, too. I assume they're meant to be rpg style pseudo-overhead sprites, though, and if they are, they look too 'straight on', if you know what I mean. They appear to be staring straight at the viewer, as opposed to slightly down which would be straight ahead if we were looking at them from above.
In case that makes as little sense to you as it does to me re-reading it, i made a small example:

Currently, they're more like the one on the left, while the one on the right give more of a 'looking ahead' feeling, based on the assumed perspective.
Sweet sprites, though, and if they're not merant to be semi-overhead, even better. I'm really liking them alot so far.
