Hey hey – that is correct; submitting the old 250 box challenge, and the newer 50 (which are more representative of your skill level), is the correct way to go about it, by the way. For now, let’s start by looking at your lesson 1 submission.

Your superimposed lines look great. They’re smooth, properly lined up at the start, and of a consistent trajectory. The ghosted lines look quite confident, also, though you’ll sometimes course-correct near the end. Try to avoid that, mainly by being a tiny bit less conscious of the end point.

The table of ellipses exercise looks fantastic. Your ellipses are smooth, rounded, and properly drawn through. I do wish you’d had more than 3 total degrees that you cycle through, but that’s alright. The ellipses in planes look really good, also – they maintain their previous smoothness/roundness, despite these more complicated frames. Their rotations don’t do as good of a job of matching up, but that’s normal, and something that’ll improve through mileage. The funnels could’ve used a tiny bit more ghosting, looking at the occasionally misaligned ellipse, but are looking good for the most part. Consider having the increase in size be a little more obvious, in your next attempts.

The plotted perspective exercise looks clean.

The rough perspective exercise is really well done. Your linework is confident, your convergences solid, and, more than anything, I’m happy to see such clear evidence of patient, thoughtful planning on the page. I have 2 pieces of advice. 1, don’t extend the correction lines beyond the horizon, just to it. 2, be mindful of the shapes of your planes (specifically, of the fact that the near/far plane have (should have!) the exact same shape). For an example of this not being the case, look at page 1, frame 2, right-most box; its front face is a rectangle, its back face a square.

The rotated boxes exercise rotates a little too much, too fast – so much so that you weren’t able to add the 4 diagonal-most boxes – but that’s alright. Ultimately, what we’re looking for is an exercise that has been seen through to the end. This one demonstrates a good understanding of 3D space, what with the boxes being snug, and rotating comfortably, and quite a bit of patience, too, from the points, lineweight, and hatching. Solid work. Do draw a little bigger next time, though.

The organic perspective exercise looks great. You’ve got some interesting compositions here, and the many overlaps do a good job of selling the illusion. This is aided by the size, and foreshortening of your boxes, and the boxes themselves are mostly correct, too.
