Last minute entry, did something similar for a side challenge a while back... I know I'll get dinged for the shadow and background, but this was just for fun (and I couldn't think of anything else!)
Quite a nice take on the challenge, the only downside is that harsh shadow right behind the bottle / splash, had you moved the subject away from the backdrop you could have eliminated this considerably.
Good idea. I'm surprised it wasn't used more often. Good timing. The flash is really harsh though. Move further from the wall and diffuse the flash and it would be better.
