Okay so this works fine. Congrats on completing the challenge +50 more boxes. So starting off I think your line quality throughout is pretty excellent. You are clearly using the ghosting method to great effect and you are achieving really confident linework with a good degree of accuracy and towards the end of the challenge your line weight is looking very nice as well. You showed a lot of growth in your box constructions from the first 75 or so boxes towards the end. Your first few pages had some line extension errors and some pretty serious convergence issues.

For the most part you started getting A LOT better with your convergences but the problem is that you pretty much only drew boxes with very extreme foreshortening where the vanishing points were on the page. Despite some of your early boxes looking a bit wonkier you were definitely challenging yourself a bit more with the different types of boxes you drew as you were mixing in boxes with less foreshortening where the vps were off the page. Now I'm not going to have you do any more boxes as I think you've already done more than enough and are showing a good amount of growth. But that said I think you should really try working some more boxes with less foreshortening into your warmups so you can get some more practice in with those as I don't really feel that you were quite getting those right throughtout the challenge.

All said this was a really good submission that showed a lot of progress. I'm going to mark this as complete and good luck with lesson 2.
