After previous sketch I realized clearly that my butts'n'boobies drawing skill is need to be improved. I've been taught basic academic drawing aproximatelly ten yars ago so I dicided to start from the structure. So, what happened next...?

Me: Ok, google, how to draw pelvic bones?
Google: Here, master, I've got youtube tutorials, pics, 3D spinning gifs, MRIs of bone cancer...
Me: Enough. Show me.

*few moments later*

My brain: *bluescreens*
Me: WHAT THE F*CK ARE YOU?!

*seven tries later*

Me: Okay, I think, I figired out it somehow.
Google: Congratulations, master!
Me: Shut up.
