Hello, Since I didn't saw the reference you used, I tried and guess what was going on . I'm pretty sure you headed for a 3 point perspective of a hallway and I can already tell it must have been such a challenge. Nice attempt. You spotted one of the most evident landmark (the doorway) to help you figure out the environment and that's a great idea since it gives more character as well as clear and understandable structure to your drawing. Regarding the perspective it seems a bit fish eye like and I would suggest you to tackle the 1 point and 2 point perspective before heading to the final boss. (3 point perspective) I'm pretty sure it's a lack of 3D space awareness which is no huge deal since you seemed to understand part of the effect, the proportions looking nice and so I would just recommande practicing the old fashion boxes, cylinders and forms manipulation in order to sharpen that spatial awareness. (the other great exercice you can practice is puting forms together with cross section and try and cut them out or add them) Hope this feedback will help you. Feel free to reach me on the discord. | Artwod Feedback
