Absolutely amazing mock up! The amount of motion-blur and energy you are putting into the animations, not to mention the palette, reminds me greatly of the Mega Man Zero series. Erm, now that I look at it...I also see a sword, gun and shield-thingie in the upper right....great execution and good nostalgic factor!
I like the preview better then the piece as a whole.
I agree with Christoballs but the animated sprite is excellent-looking
It's maybe just an impression but it doesn't look finished.
In all honesty, I think the color choice is pretty bad in this :p
Looks sharp.
