Hey there! So, I'm still new to composing scenes and doing convincing depth, but hopefully some of this is helpful. Main things I did for the scene at large was I lightened up the door and the cubbies furthest away from her, as things in the background are typically lighter than those in the foreground, especially when you have a light source coming from the background. This also helped to make her dark values stand out more from her surroundings. I also decreased the glare on the table and moved it, because it was getting confused with the hard rim light on her coat. And, with that change, I also lengthened the shadow of the bag to try and add more depth. Since I wasn't too confident in how I could add more depth to the scene, I felt that the character herself could use a bit more depth. I mainly did this by giving her bigger occlusion shadows, most notably under her jaw and around her hair, but also on her scarf. And beyond that, I tweaked her face a little. Her eyes were a little too close together, and the top of her head was tapering too sharply. I also brought her ear up a tiny bit, and raised her chin a little. Hope this was helpful!
