This is beautiful, very clean and with excellent details. The roughed-up quill and few stray hairs on her bangs add a lot of charm, and the glasses came out great, especially as she adjusts them. She's even more of a nerdfilly. The glow along her edges makes me think she has a standing hooded lamp so she can write while keeping the room from being so bright it makes her patient uncomfortable. Well... I'm just guessing here.
The only little thing is that that the main portion of her cutie mark is very hard to see. It could just be a combination of my color vision and the shading, though at least the vertices of the white star under her purple star should be visible. Then again, it's not appropriate for a patient to be staring at her rump anyway.
