I'm a bit iffy on this one. Yes, it looks very pretty just in-your-face "oooooh" but on closer inspection the illusion breaks for me pretty quickly. Her clothes are obviously not wet, nor are the curtains, etc.
It's better than the photos I ever take, but it's AIMING even higher than that, so in terms of delivering on a promise, it backfires a little bit to my eye.
Would have been a lot more epic (although I understand vastly more difficult and expensive) to shoot her actually underwater then edit in. Also possibly the curtains underwater (could use lime green ones in a pool and reverse-greenscreen them in as white here). Fabric underwater simply looks hugely different than anything you can accomplish with a fan or gravity alone.
