My commission is:
Pregnant pony shining armor in labour.
He is is laying on his back and spreading his legs in a "birthing position".
His member is fully erect.
He is sweating and panting because of his strain / exhaustion. (the pose reference gives a good idea)
His belly is more "roundish" like the one of a full term female.
There is a X-ray projected over his body (no separate frame) which shows some of his internals.
In his "womb" (it doesnt have ovaries) that is connected to the urethra is a changeling, who has some of his features, like his hair and light skin. The changeling also has a Umbilical cord, and a swollen belly with some veins going from the base of the cord (kind of like a yolk sac). It is in the birth position, barely leaving the womb. Just the horn has left it, barely stretching the urethra outside the womb.
If possible i would like an alternate version without X-Ray too. The belly looks stretched to its limits and has a "blush" on it. (its a slightly irritated reddish area around the popped belly button.)
