Alright but can improve.
Firstly, I like the air of mystery to this drawing. It adds significantly to the girl standing there.
The main problems I would see would be to make the shading more prominent, and to adds something behind the curtains. Nothing big, but maybe an odd room fading to black, which would increase the feeling of mystery even more.
thanks for the compliment and tips!
