Whose Butt Do You Want To See? (Patreon)

For a long time I've been wanting to make a tutorial on how I draw the rear ends on ladies.  Showing how to draw different angles, why it looks the way it does in different positions, do's and dont's, etc.  This is something I'm slowly gonna work on here and there in the future, which will be hosted by my character Tambre, but I want you guys to recommend which characters behinds will be shown in the tutorial.

So whose butt do you want to see?  Keep it to Sonic girls please, and list as many as you want.  Preferably list your top options first.
