So like I said previously, I'm still in the mood for some princess exposure!
Though the end product is a pretty crowded piece, this pic started as an aside doodle:
I liked the idea but tweaked the pose a bit...
Once I was satisfied with it, I cleaned up the sketch:
I then added Bowser behind her to hold her legs up; but at first only his hands were supposed to be fully rendered, with his less defined body intended as the sole background:
...But after I added the fully-shaded Koopalings in the foreground, and a proper background behind him, he looked out of place so I went back and added some details on him:
All of that took a hell of a long time, but I kinda like how it turned out.
Btw, this isn't the first time I draw this scenario:
...And this isn't the last time either, I started sketching a prequel pic too:
It started as a simple panel but as I was adding more and more characters and expanding it, it evolved into its own solo pic.
