Damn, are you challenging me? Because I fear that this time I will lose, lol!
Well, surely you've provided a nice picture but I don't think it's applicable to our case. That poor girl is not shooting turds as large as her bum and as massive as her body. Of course, I am not talking about anatomy. That would be a plain and simple nonsense. However, there's an "inner consistency" that a drawing must preserve in order to be good looking. What does it mean? In our case, it means that an ass must be recognizable even if it's stretched in absurd and inhuman ways.
And all this boring premise is just to say that I don't know what to do! I can't think of a way to effectively fit a volcano-shaped ass in this drawing. Furthermore, it would end up looking like a prolapse, thing we both don't like. However, I think I understand what you did not like about the previous drawing so I did a couple tests. I hope that one of them is satisfactory enough.
