I bet you can guess what my comment will be. Your rendering of the curtains make them look pointed as they turn. Soften the edges! They are almost the least important part of the picture. Hard edges grab attention! You don't want me spending my time examining the curtains. That isn't what this piece is about and frankly I think curtains are boring in most situations.



Soften the tree trunk outside, the wrinkles on her skirt and the FORM shadow on her arm.



Form shadows have soft edges XD. Cast shadows are where hard edges come into play and even then those get softer as the shadow moves away from the object casting it. Think in terms of 3D: highlight, mid tone, core shadow, shadow and reflected light. That's how you get objects to turn. You could benefit from applying it to the figure.



Her feet look carved out of wood. Feet are kinda of in the same boat with hands. Viewers eyes are attracted to them. They are worth nailing. But, of course, they don't come before hands and faces so use softer edges on them. XD



Your values are excellent.



The kittens are adorable and done very well. However I question the pads on the arm extended on the kitten standing up. Cats have a pad for a thumb and I think they have four toes, not three. (Unless I'm wrong or your kitten has a birth defect.)
