Hello, hope it's not too late for you to receive feedback!

  • Your line work for most construction lines and hatching lines were done pretty well. But there is some wobbling here and there. If you're not spending enough time ghosting, I'd suggest slowing down a bit so your arm can process what it needs to do. Also, if you feel like you messed up a line, don't try to repeat the stroke in order to cover up mistakes. Just move on and aim to not make the mistake in the future.

  • You've applied the convergence lines correctly. Nice job there

  • Very nice experimentation on the angles/orientations of the boxes. Keep that up, as drawing from multiple angles will help your understanding of 3D space.

  • Nice experimentation with the dimensions of boxes (L x W x H). Next step would be to experiment with drawing boxes with equal lengths, widths, and heights (basically drawing just cubes).

  • Your understanding of line convergences got better over time. There was no real problem of having lines diverge.

  • Your back/inner corners got better as well.

  • There were some cases where the lines were too parallel, as opposed to converging.

  • I'd suggest experimenting with more shallow foreshortening. I noticed that most vanishing points were either on the page, or very close to the boxes. Not that that's wrong, but it would also help to try drawing boxes with far away vanishing points (to the point where the VPs would go out of the page).

  • When tackling shallow foreshortening, keep in mind that the lines will still not be parallel when drawn. When drawing any box, the lines will still converge, if even just a little.

  • If you're having trouble with estimating how much a line will converge, here's a diagram that can help: https://i.imgur.com/8PqQLE0.png
