Serendipity, I guess, that I coincidentally got around to it and drew some stuff shortly before I was hospitalized and the only non-pony thing I drew worked perfectly with just a few modifications. Navel is about a 2" incision accounting for the radius of the cut, the other two are maybe one inch. The drainage tube exit thing (which would be under my palm there) is what weirds me out the most because they just pull the tube out of you in your room and put a gauze pad on it and say it should heal closed on it's own, because you know, you have an open hole in your body, ewww.

The basic details.
