Not bad, I'd say that you need to spend some more time drawing your backgrounds. For example the cupboards in front of the doctor looks completely wrong, it looks like it's wonky. And the bed that the prisoner is siting on looks to be quite frank rushed. I'm also not a fan of people using a picture in there artwork so draw the area through the door. The officer needs work too.
I'm not being harsh, you understand? Just critical. This is good but it could be improved. You are improving in general and your other pieces are coming along too. Keep it up.
