Nytro pinup variations (feedback!)

So here's the few from-scratch doodles I did for this pinup. I originally thought perhaps the hot-tub pic might be a nice pinup, but I kinda wanted to try some fresh material first, and I really like all of these. The right image was an unused pose for Talia(female Nytro), and I thought would work well for his male form too. You guys wanted butt shots so here they are!

I've attached a few files with parts moved here/there, because I'm curious which versions of which images, as well as which image overall, you might prefer. Some of them could have alternate/variations like undergarments(he usually wears boxers/boxer briefs), cum or cock shots/toys/expressions. He's a switch, but that just means he can become submissive, not necessarily 'girly', so I don't think lingerie or panties is in the future...for now anyway. Enjoy!
