Hey there! You made me think that the stairs one, it was tricky. But I believe this would be the solution for it :) Regarding the C shapes. You didn't do wrong; both look great. The perspective of the right one was slightly off, but it was okay tho. Regarding how to draw both planes and keep the same size. I'd do something quite methodical. Trace horizontal lines on each vertex of the top C, and then draw vertical lines. Then just draw the projection and connect both planes. Hope this helps! | Artwod Feedback
