Hey guys I’d like some advice about this piece I’m working on. I’m trying to draw the scene from Harry Potter 1 where he encounters the goblin roaming the halls. I was trying to convey a feeling of being dwarfed by the goblin. For some reason, the perspective seems off and the walls feel very empty. Also I wanted it to be nighttime with the moonlight shining from above, but the colours feel off. I did use a 3d power app to help as a ref but it feels very stilted. How do I fix this?

Thanks for your help.
