Hey! It's cool to see your progress from the very first exercise (just the lines) to the planes; it looks like maybe you felt more confident with drawing lines quickly and steadily by the time you got to that one, which is great.
It looks as though drawing ellipses comes more naturally to you than straight lines (the opposite of me!); your ellipses feel loose and smooth, but you seem less sure for the perspective/box exercises. Your actual non-guided perspective exercise has some really good guesses for vanishing points, but it seems like you were focusing more on getting the perspective right than drawing strong, confident lines (not that it's right or wrong to focus more on one or the other). I am sure the line confidence will come with time.
Nice job!
