Hello :) I think a first step you could take is train to draw straight lines, here I think you unconsciously wanted to reach a certain point and some lines curves themselves in order to achieve that. If it is hard at first you can start with a ruler. If your 2 vanishing points are too close it will give the impression that the angles are a bit squished. Also it is hard to draw perfect squared box, you will draw rectangles ones at first, keep at it and use reference to get proportions rights. | Artwod Feedback
