Good work.

Try to focus on lines, and ghosting method, and always start from same point. You got that, but be more confident with Ur hand, because u try hard and that makes lines wobbly. Try to always prioritize confidence over accuracy. On your ellipse tables u should do more variety of different angles size and degree of ellipses keeping in mind that they need to stick to each other. Good job with one and two point perspective exercises. On the rotated boxes exercise You need to rotate every box, the far ones looks alot like the middle ones, try to rotate them more. And the last thing is in the organic boxes exercise. U were overcomplicating it for yourself, that basic line shouldn't pass through itself, it can but it's more complicated to put boxes on that line in good perspective order. I think those are Ur major problems to solve. Although you did well, and don't feel like U fail something, errors are acceptable, just be aware of them and try to improve.
