Hello and congrats on completing the challenge. I'll be taking a look at your submission. So starting off despite your failing pens your linework is pretty godo throughout this challenge. You are using the ghosting method well and are getting smooth and confident lines throughout. You are also doing a great job extending your lines back on your boxes to check your work. I noticed a few inconsistencies with this in your first 50 boxes where you were extending lines incorrectly but that appears to have worked itself out as you continued with the challenge. So great job there. Your hatching does feel a bit rushed and it gives your box a sloppy appearance. At this stage you should really treat your hatching the same as you would the rest of the lines you draw. Ghost them and draw with confidence. I know it seems tedious but it will help you build up the muscle memory to do it more quickly. Right now it looks you are trying to do them at a quick pace and it really shows.

Finally, getting to the boxes themselves there is for sure improvement when it comes to consistency with your box constructions while you worked through these. I am however noticing a few trends that I want to point out to you. So you are starting to rely on parallel lines a bit much and in your reliance on them you are actually causing your lines to diverge instead of converge to a common vanishing point. It's pretty apparent in #236, 194, 192, and others. Please take a look at this graphic https://i.imgur.com/8PqQLE0.png In doing so it's really making your boxes look like they are getting bigger as they move back in perspective when in reality that's not how boxes in perspective look. A box in three point perpsective will ALWAYS have sides CONVERGE to a vanishing point and never diverge and if even if the lines seem parallel because the box has very little foreshortening they are still converging even if it's just by a tiny amount. If they aren't converging that means the box is getting bigger as it moves back into space. So this is something you really should be trying to think about every time you are constructing a box. So while your boxes are looking fairly solid on the whole you still could use plenty of practice on these so keep doing them in your warmups. Good work overall though. I'm going to mark this as complete and good luck with lesson 2!
