Long suggestions and critic ahead hope you don't mind:

- Couch perspective is off, but the window, shelves and wall is good.
- Less harsh black stroke on the curtain because it made them look dirty. It's better to focus on the overall shape before texturing too much on the inside.
- The shape of the hand and finger holding the book can be made better if you referenced it from yourself in the mirror
- Some objects in the background have inconsistency in shapes. (For example the black vase)
- If the objects in the background can be a little more neat (the lineart, the messy arrangement is good ^^) it will be more pleasing to look at.

Hope that helps
