Let me start by saying your art is amazing, sexy and inspired. I'm a big fan!
Oddly enough, there's far more relevant research concerning bipedal humanoids with digitigrade legs: Google the stilts people make for costumes and you'll find both functional systems and a great deal of analysis on the physics involved. Skeletal makeup is important for realistic art and these devices are a good projection of what could be. That said, suspension of disbelief is an important part of enjoying sexy saytrs. Cheers! #2c
I love these two characters so much I have been kicking around the idea of writing fiction inspired by them. The dynamic is just so intriguing, both for fucking but also general interaction. I love the little hints at this you have dropped in other pictures, maybe leaving something to the imagination is better?
Nah! I really want to see you do a comic. I know it will be excellent :) Maybe I should e-mail you about commissions.
I like the short hair. I agree with the poster above that I prefer long hair on a girl. But if you carry over the TG theme from the sister image I think the short hair fits better.
For me hair style is a bit along the line of clothes. If somebody were to change gender why would their clothes or hair style change? Over time yes, but those things are sort of separate from biology.
Absolutely love this piece. Even have it has my wallpaper(more pixels would be nice, pretty please!). The ONLY thing I would change is having her grip the sheets a little harder with her left hand and flare her toes out a bit. She looks like she is getting overwhelmed by the (possibly unfamiliar) sensations and the act, its captured so well! Well artist, what is her story (once a guy maybe)? Why is there coercion?
besides that small detail I agree with everyone, of course, you're so gifted. An alternative version of her slightly gagging on the way down would really make my day.
