All right, I downloaded it and here it comes:
THE NEXT EPISODE OF BLUE PHOENIX'S BASHING!
Just kidding, I just found the title fitting :P
anyways, the face-pic... yes, we all know it too good :P
I guess it wouldn't be too bad if you add a neat gradient as the background, and make the transitions a bit smoother. Wait, you're using MS Paint, right? Well, trash MS Paint and get some tool to make it anti-aliased aka. smoother :P
The _s-pic... looked kinda... strange to me. You should it really make more like the other _s-images, or, at least keep all sorts of weapons out of the picture and move the head into the middle.
Other sprites... not much to say besides that they are fricken' AMAZING! Just that thing about the fire and ice looks unreal, to be brutally honest, the ice looks a bit like a box and the firse like some red plants. Please don't be offended by that, it's just my personal opinion
Concluding result: good sprites so far, not much to complain about. Keep up your good work!
