I think it’s a good start.
I think you need to focus on better defining things. Like the couch/beanbag thing, that should have more details and shading. Or how there is shading on the girl’s arms but none on her legs for some reason. It feels very inconsistent on what you are picking to add shading to.
I think it could also be worth experimenting with different compositions. Like I don’t know if that thing behind the blonde man is a door or the back of his chair.
