Well, at the very least it's creative, eh? I do wonder a tiny bit about the subject. Is this usual to take a bath with flowers? I saw all the rose petals in the tub in American Beauty, but this is a bit different. ;)
But going with the shot, a few things. First, could you have actually reversed yourself in the tub and shot with your foot on the other end? That would remove the drain. I think it's an extraneous element and distracts. Removing as many unnecessary elements as possible is always a good thing in my mind. (With that in mind, the pink container in the background might qualify as well. I didn't find that nearly as bad though.)
I like the polish. But I guess that's my personal taste. ;) Here's a trick you can try. Use "Filter>Noise>Dust and scratches at a very low setting to try to remove some of those tiny highlights. Sometimes things can look a lot better after that. It's even basic legal (in case you need it for those challenges).
I would love to know how you did the whole setup. Did you use a tripod, get settled into bath, with just one dry hand sticking out to reach the shutter or remote?....Whatever, it's quirky, indulgent, colourful, different, fun,... and just great! Well thought out.
Hummmmmm...... I really don't know what to say on this one. it's quite messy looking the crop and everything. I'm not a fan of the black toenails either. But if you would have captured the flower itself in a nice macro with the toes or the bather out of focus in the backround it would be a winner
Wow! Good Job! What a pleasant change of pace from the sea of flowers that I've been looking at. My fav so far, and I'm 80% thru. Nice use of color and lighting. Wish the toenail paint was a different color, but hey, that's just the female tastes coming thru. Good one!
