Hey Iceblocker,

Lines

A nice effort with super imposed lines. But for ghosted lines you have some frayed ends that don't connect (at least) with the start point. Also make sure your lines don't wobble. They should have a smooth flow from one point to another. For ghosted lines, when marking down the points just place tiny dots on paper instead of giving a focus on them and making them bigger.

Ellipses

Ellipses don't have a wobble and are continuous. Good job on that! But when drawing them make sure you go through the ellipses 2 or 3 times. In the ellipses table, the ellipses should be kept within the bounds, each ellipse touching each other, without overlapping. On funnels, you've mostly done it, but don't forget that the minor axis has to cut the ellipses in 2 identical halves.

Boxes

On rough perspective, width lines should be parallel to horizon and height lines perpendicular to horizon. I know this might be hard, but make sure you keep this in mind for the future. For rotated box the corners for different boxes need to be at a close distance with each other. For organic perspective try to keep a consistent shape for the box. 250 box challenge will definitely help you tackle the rotated boxes.

Have a good day :)
