OK first I gotta say I love the lighting and the poses. That shit is all mint as hell.
There are way too many folds on that dudes suit though. Like they're not wrong and they are all well rendered but they are giving the impression of something I don't think you intended.
Suits are fairly thick material that does not fold or crease that much during movement, it would really only be showing visible folds at extreme points like the knee, bent elbows etc. Everything else is going to try and hold its shape. It's kinda the point of suits is that they provide a tailored silhouette for the person wearing it.
With the excess folds though it makes it look like a different kind of material and outfit. Like it almost reads to me like he's wearing loose silk pyjamas rather then a suit for ballroom dancing.
It can be kinda hard to see on reference photos cause they're black suits but if you zoom in you can see that like other then a couple of folds around the knees and elbows the rest of the outfit isn't really showing that.
