Hello! Congrats on finishing lesson one, it's the first checkpoint yet a checkpoint nonetheless! I'll break this down per section.

Lines: Your superimposed lines are solid, albeit some minor fraying at the beginning of a few lines, but overall doesn't appear too much. Your ghosted lines aren't too shabby either, but as it goes into ghosted planes I'm noticing a focus on accuracy. You got from point A to B, but I see significant wobbling in these lines. Remember, we're trying to put confidence first: after ghosting for as many times as needed (and maybe a few more, just in case) be sure that your stroke is fast and straight. It's easier to work on accuracy afterwards.

Ellipses: Your table of ellipses isn't too bad, there looks to be a good amount of confidence by the end of it. Just to mention though, even though it was only a few sections, cramming a bunch haphazardly into the zone isn't what the exercise calls for; it feels nit-picky to say though since it's only 2 out of the 2 exercises. I see a dip in confindence as you reach the ellipses in ghosted planes, remember that making sure the ellipse fits perfectly within the section comes second, as making sure it's smooth and confident all the way around comes first. This issue persist in the funnels exercise too, though I will say you did a pretty good job at following the minor axis.

Boxes: Plotted perspective doesn't have much to comment on, you followed the vanishing points correctly. Though I do see minor improvement within the rough perspective exercises, it's important to remember the properties of the lines you're drawing and where they apply, especially within the planning phase. Within one point perspective, any line is either:

• Parallel to the horizon,

• Perpendicular to the horizon, or

• Pointing towards the vanishing point.

  Depending on which part you're at in constructing a box, you'll have to think about either 1, 2, or 3 of these properties with different lines, so try to make sure you have all corresponding rules and lines in check when planning your points. Moving towards your rotated boxes, it looks like you're restraining yourself with rotation until it gets to the outer rim of boxes. An example would be the first box to the right of the center, where it looks thinner, not rotated. This was a hard one, no doubt, so if you attempt it again for a warm-up focus on what it would mean for the box you're about to work on to rotate the way you imagine. The vanishing points will have moved, so your lines should reflect that. Lastly, your organic boxes; again, a tricky exercise, but I see a lot of parallel lines. If you follow any set of lines that would be parallel in 3D space, they should all be pointing to one point. Remember the plotted perspective exercise, where you could see those lines reach that point. After you draw a Y to start your box, think about how the lines of the rest of the cube should be pointing. A personal tip that I like to mention to give a starting point; when you add the planning points for the points outside of the Y, look for where they would be parallel with the Y lines, then tuck that point a little bit closer to the center of the Y.

  That was a lot, but I think that means there's a lot of room to grow. A lot of these issues can be improved on as long as you keep up with warm-ups, and your approach to perspective can be refined through the 250 box challenge. I think you're clear to move on, just keep up the effort and you'll be golden!
