Hello ! I am far from an expert but here are some pointers I found : 1. your perspective tend to curve the more you go left. I don't think it's intentional. 2. For the depth of window you can use the perspective lines (green) 3. Your window are across the horizon, so you will see the top plane of the window (in Blue) 4. If you check with a basic cross you see the door is not centered between the windows (it is not an obligation but it takes up place you could have use for the left window) 5. You could add a second vanishing point for the lines inside the window (optional) (and the floor) 6. The square on the floor should get smaller the more you go away (to be mere dots near the horizon line) I hope that helps.. | Artwod Feedback
