@celia: I thought the same about the curtain, but It isn't the contrast. I think I'll change the shading and the color (a light-blue).

Thank you for all critiques. The next time I won't do the same errors.

I think they're in right way, but I had a lot of problems with the shadows; maybe 'cause I've never made shadows in other PA.

Thank you for your collaboration.

There's a white fastidious pixel on the neck.
