Super Mario 3, revamped and extended

[Iceman404]

The sheet is nearly completed in terms of actions; all that's left were the throwing animations.
Here's a remade Bowser shell to tie you over.

The spikes need to be more exaggerated as to cover the plain shell, and the rim of the shell (the white seal) should be thicker, it could also use a bit of smoothing with anti ailising. The bottom part also needn't to be cut off there, it'd look odd used anywhere besides the ground with that cut off.

I like where this is going, you're moving from edits to nice custom stuff.
