Hello, Battleground. Congrats on finishing a tough challenge. Here's some feedback:

• There are some different orientations for your boxes but I think you could benefit more from drawing a variety of orientations. This will help later down the road when you draw objects from different angles / perspectives.

• Some of your convergences are nearly parallel (e.g. Box 250, 246, 245) .This wouldn't happen in 3D space, so remember to make sure that your lines converge (it doesn't have to be super obvious but make it noticeable).

• Some of your line extensions are also incorrect (e.g. Box 250, 177, 196). For these boxes, the line extension should be downwards, not upwards. This is because the lines should be converging away from the viewer (the top plane of the box is still facing the viewer - kind of - and so the lines converge downwards).

• Good attempt at linework, but some lines are a bit wobbly. Remember to ghost, use your shoulder, and go for confidence.

Overall, good attempt at the challenge. Looking at your progress from Box 1 to Box 250, it's clear you're getting the hang of how boxes sit in 3D space.
