personally enjoy the Futa/Selfcest scene greatly. Though the penis seemed a bit off. :l Perhaps a less pointed and/or more human like and/or rounder headed penis. Also, props on the vagina, it looks nice and I feel there's not enough visible vagina on this site. Also, I love the nips and vag not there when moving about, but appear when she's getting horny for the mirror and painting x3
Now to constructive criticisms!
I find in the futa seen, that the vag, penis and stomach bulge are a bit off set, I think it's a smidge too far to the left. Or on Dusty there, too far to her right >< Also, for a split second after coming up the stairs from the basement *assuming it's a basement* you see the rag on the top right corner, and the exclamation mark above her head. Hoping it wont become an issue later on so I felt it necessary to mention it for the sake of this games completion.
EDIT: Also, as you mentioned on you blog about the backgrounds, I think they are perfect. Also, I think the current colors are just right and shouldn't be changed. And, I just love the shade of pink you made the cum, perfect contrast with the gray, perfect!
A bit more CC rhe bulge seems to fit penis shape too perfectly IMO seems too unnatural, as if either the flesh between her vaginal cavity and skin is paper thin, or she is so ungodly tight it actually shapes around the penis...painful >< Also *personal request warning* add a little more cum ^^
