I don't know why no one else has commented, I think these are awesome. Good work!
For me, taste-wise, the animation could go a little slower or maybe have more frames. Playing a game there has to be a satisfying "Oh I just beat your ass down with my button mashing" feeling to the attack, and these feel like pressing the weak attack button in Street Fighter II. Style-wise for some it may work, but a bigger, beefier attack would be nice. Still, I like the animation a lot.
The art's very nice, as well. My critique is similar to the animation. I feel like you're holding back a bit; it comes off a little flat (some shadow behind those pillars, even if they're intended to be inset) and a little thin (the wood elements, particularly, would benefit from some added visual weight). I see a Dracula X / Rondo of Blood type vibe here, nonetheless, and I'm very enthusiastic about it. If you use none of what I've said I think it's very strong as it is.
