I really like the cubic style of colors in the background. I've been looking over a couple of these previous pictures, and the colors really stand out to my, but the pattern in the background of this one seems really well done and wonderfully imaginative. Oh, and Inky is awesome. That too.
The following is a musing on Pony reproductive organs. (Jeeze, if I'd put those three words together a year ago, I would've slapped myself. Though to do that I would have required a clone of myself. Awesome!)
Put *here* because - well, where in the hell else am I going to put it?
The reason Poni have smooth undersides is because pegasi and/or alicorns evolved first, and they needed a drag reduction advantage - a tiny advantage that added up over long flying distances. The reproductive organs became smoothed over by an aerodynamic membrane. During reproduction, the sex organs open along / punch through a small slit in the membrane, and are exposed to open air just long enough for mating (in the literal sense of the word) to occur.
I'm basing the male organ, at least, off the weapons system of the F-22 fighter jet.
Le Wiki: ...Carrying missiles and bombs internally maintains its stealth capability and low drag, resulting in higher top speeds and longer combat ranges. Launching missiles requires opening the weapons bay doors for less than a second, while the missiles are pushed clear of the airframe by hydraulic arms. This reduces the Raptor's chance of detection by enemy radar systems due to launched ordnance and also allows the F-22 to launch long range missiles while maintaining supersonic cruise.[link]
One thing: It looks like the Fee's hind left leg punches straight through Wan's midsection. And because the 'sketchiness' of the drawing, she (?) looks like she's wiggling her leg a bit with pleasure, as though not a single fuck was given that her leg's *through* her lover, because she's going to enjoy this first.
Oh, btw: I'm working on your commission, so sorry for the delay ;A; It will probably follow this week. Fortunately I elaborated pretty nifty digital style over last few days, as you can see, so I'm ready to experiment with the piece for you
