I really like your coloring. It's really peaceful looking :3 She has such a gentle expression.
And I'm not extremely good at anatomy, but I'll try to redline. So if I say something you don't agree with, you don't have to listen.

I thought her collar bones made too much of a v shape? I can't explain it. I just straightened them out a little. The arms were just a little short. If they were a little longer, then it would be fine.
Ignore the lower half of the body redline because I didn't read that you wanted to keep it the way you had it. I really like the legs too.
This is a really pretty composition, I'm sorry it took so long to get a redline
sad Hopefully someone else with more skill will come help.
