Choo choo train (Patreon)

This was my half of an art trade with Crabpatine / @Nsfcrab. I don't normally do multiple layers of sketches with different colors, but for something like this it was really required or my sketch would be indecipherable to me.

The whole arrangement doesn't quite work given how they're lined up, but I went with what I thought looked better than what would be more accurate. Otherwise it'd just be a complete body sandwich with next to nothing showing (actually that may've been better, more implication, but I'm simple-minded and just portraying it in plain view made the most sense, haha).
