Characters In a new style

[DioShiba]

Does his face really need the shading around where his mouth should be?

Also I would consider also making minor adjustments to the size of his legs, you could probably get away with making them a pixel or two wider and still have a good sprite.

But other than that the sprite itself is a good start, just be sure to look at the reference you are using and ask what other adjustments you think you could get away with.
