I have to agree with April again. It's easy to see once it gets pointed out. It is as if someone has made the outer part of the clothing stay exactly 1 half inch (for example) away from the white part all the way around (when we know in actual practice, we would never see that sort of hang in clothing).

Also, I've added just a touch to a very small detail that I think helps a bit. It bothered me that the extreme left and right edges of the bottome of the robe, the white part, was so bright right on the very edge. So, I touched the left side up (about the only painting I'd ever try wink) to show what I mean. So, on the left, the tiny bright edge is gone and on the right, it is still there.

Also, there look like there are waves/rolls in the lowest part of the white garment, as well, so they should be shaded where appropriate.

I hope I've helped you with your painting. I'm not much of one myself so I hesitate to give advice. I have stepped in here to speak of something I don't know much about because you seem like a very nice person. Hope you keep at it and don't get discouraged.

Cheers!
