$8!

300x300 and 100x100 versions provided. Very simple shading. No changes unless I miss something from the description or ref, so be specific if you want a given expression.

Note or comment with your ref(s) please.

Bonus: these three icons shown are freebies, so if you have use for them, go nuts. Just please don't claim the work as your own. Cutting them up or resizing these three for your own use are up to you though. ;) Very easy in MS Paint.
