Your superimposed lines are good for a beginner, well done there. Your ghosted lines seem to wobble and miss only slightly. To help with that, ghost your lines more until you feel fully confidant. You don't have enough ghosted planes, they're too far spaced out. The page should be completly filled. Some of the lines are kinda wobbly too, or have inaccuracies. I think your tables of ellipses are good, but they do lack variation. If you revist that exercise please try to vary up your ellipses a little more. Your ellipses in planes also need to be redo, not just for the above reasoning but because they do not follow the plane well. Your ellipses on the elongated planes do not match them. Your funnels are good but lack variation. Your plotted perspective has no where near enough boxes, there should be 4-6 per page third. In addition your repeadtadly crosshatched the wrong side of the cubes. You must crosshatch a single side facing the viewer. Your rough perspective improved quickly, but your lines wobble severely and sometimes miss. Be more confident with your lines and ghost more. Your roated boxes aren't really rotated. If you revist this later such as afte rthe 250 box challenge, I'm sure you'll do much better. You only have one page of organic perspective. You shaded 2 sides instead of one and all your lines seem parallel. Makes the lines converge with each of the Y lines.
