Glover 64 sprite sheet

[megaMasquerain]

At this point it's a bit hard to see how the sprites look because they're not animated. I guess my main critique would be that the shading/colors are rather bland. I know Glover is white, but adding a tiny bit of a tint to the shadow color and making it darker so it contrasts more nicely with the white would be a good idea. The black outline is also a bit ugly, but darkening up the shadows might fix that, and I know if this is meant to be used in games it might need a dark, solid outline anyways.

Can you link to AJ Nitro's original sprites? Would be good to have as a reference.
