Nice! Very good!
Just 2 details that bugs me:
1. Where is black looking at?
2. Black looks red as a tomato, even though I wrote "the red of fury is still rather noticeable. Not "red as a tomato" but some angry red."
Everything else looks great! The hip angle forward to give emphasis on her anger, the arms are well in place too, pink looks good with the legs stretched like that. You remembered the penis! Pink's neck almost back to normal but not normal is also great!
The workaround of hair from black's back is fine too. Maybe my reference wasn't good enough and was too open for interpretation... Even so, I like it how it turned up.
I'll be working to provide you the next reference next week/month.
Thank you!
