Hello and congrats on completing lesson one. My name is Rob and I'm a teaching assistant for Drawabox who will be handling your lesson one critique. Starting with your superimposed lines these are off to a fine start. You are keeping a clearly defined starting point with all of your wavering at the opposite end. Your ghosted lines and planes turned out well. You are using the ghosting method to good effect to get confident linework with a pretty decent deal of accuracy that will get better and better with practice.

Your tables of ellipses are coming along well. You are doing a good job drawing through your ellipses and focusing on a consistent smooth ellipse shape. This is carried over nicely into your ellipses in planes although you are deforming some of your ellipses at times. https://drawabox.com/lesson/1/17/deformed You are compromising your overall ellipse shape by adjusting for accuracy midstroke. Try and rely a bit more on the muscle memory of the motion you build up while ghosting and almost make your mark without thinking. This will be less accurate at first. Although accuracy is our end goal it can't really be forced and tends to come through mileage and consistent practice more than anything. Your ellipses in funnels are looking smoother and I'm not seeing any real issues here. One thing you could have done with these is start with a narrower degree ellipse in the center and then widen the degrees of the ellipses as they move outwards in the funnel. Please check the example here. https://drawabox.com/lesson/1/18/step3 This helps with practicing different degrees of ellipses. Your ellipses are off to a great start but there's still room for improvement so keep practicing them during your warmups.

The plotted perspective looks great, nothing to mention here. Your rough perspective exercises turned out pretty good. It's great that you are keeping up with the confident linework on these. I am noticing that you are redrawing lines on occasion and this is a habit you should try and get out of. Try and stick with the initial line you put down even if it's a bit off. Adding more lines just makes things messier and harder to read.You are also doing a good job extending the lines back on your boxes to check your work. As you can see some of your perspective estimations were quite off but that will become more intuitive with practice. One thing that can help you a bit when doing a one point perspective exercise like this is to realize that all of your horizontal lines should be parallel to the horizon line and all of your verticals should be perpendicular(straight up and down in this case) to the horizon line. This will help you avoid some of the slanting lines you have in your constructions.

Your rotated box exercise turned out pretty well. I like that you drew this nice and big as that really helps when dealing with complex spatial problems. You did a good job drawing through your boxes but one of the reasons this exercise started to fall apart on you is because you didn't keep the gaps between your boxes narrow and consistent. https://drawabox.com/lesson/1/21/guessing Keeping the gaps narrow and consistent really helps with inferring information about neighboring boxes rotation and proportion. While the rotations here aren't perfect this was a good effort overall. The more you draw and develop your spatial thinking ability the easier these rotations are to handle. This is a great exercise to come back to after a few lessons to see how much your spatial thinking ability has improved. Your organic perspective exercises are looking pretty good. You seem to be getting comfortable using the ghosting method and drawing from your shoulder for confident linework which is great. I do have some notes regarding added line weight I'd like to share. If you want to add line weight make sure you don't revert back to using your wrist and are drawing from your shoulder with confidence. Also added line weight should be subtle so try and only go over a line one additional time instead of multiple times. Your box constructions are fairly solid for the most part and I can see you are developing a sense for how box lines converge to vps. There are still some wonky convergences here and there so the 250 box challenge will be a great next step for you.

Overall this was a really solid submission that showed a good deal of growth. Your line confidence and ellipses are both coming along nicely. I think you are understanding most of the concepts these lessons are trying to convey quite well. I'm going to mark this as complete and good luck with the 250 box challenge. Keep up the good work! To answer your question I would highly recommend supplementing Drawabox with a course that teaches you observational drawing techniques(contour drawing, negative shape drawing, measuring techniques, etc) as that is a fundamental area of drawing that Drawabox doesn't really cover.
