My first scene using Gen3

This is a scene I’ve been working on for a couple of weeks now, mostly due to starting the scene, getting mostly done with it only to realize it didnt look right, this is about the 3rd or 4th incarnation of this scene, I just wanted to see what anyone else might think, comments really are helpful.
