Hey hey; welcome to drawabox! I’ll be taking a look at your submission today.

Your superimposed lines look mostly good, though I notice that you’ve superimposed them quite a but more than the recommended 8 times. Stick to the recommended amounts, please; it’s a little hard to judge them like this. Nonetheless, they’re smooth, properly lined up at the start, and of a consistent trajectory. I do notice a little hook at the end though. Make sure that the prior motion has ended, before you drag the pen back to the starting point. The ghosted lines/planes start off a little lacking, but improve considerably by page 2 of the planes. Still, be sure to ghost until comfortable, then commit. Also, be sure to plot some start/end points for the non-diagonal center lines of the planes; all lines need those. Also also try to maintain a consistent speed throughout the line, rather than decreasing it in its second half, in an effort to not overshoot. It’s far more important for your lines to be smooth, and straight, than it is for them to be accurate.

The table of ellipses exercise is a little mixed. Your ellipses are smooth, but not necessarily rounded. It’s important to remember that that’s far more important than them snugly fitting inside of their respective frames. Ghost until comfortable, then commit. Remember, also, that they need to maintain a consistent degree/angle in said frames. Finally, try to rotate around them a minimum of 2 times (not 1 and a half!), and see if you can lift your pen off the page at the end of your rotations, rather than flicking it off. The ellipses in planes are occasionally a little wobbly, but generally do a good job of maintaining their prior confidence, despite this new, more complicated frame. As for the funnels, I’d spend a little longer on the construction itself (make sure, especially, that the minor axis is equidistant from the 2 arcing lines (it helps to draw it last)), and on the ghosting stage, too, but it seems like you’ve understood the gist of it.

The plotted perspective exercise looks a little scratchy. The lineweight/hatching should’ve been applied using a ruler.

In the rough perspective exercise, you’ve extended your correction lines incorrectly, but a closer look at your actual lines shows me that you understand what you should be aiming for, here. I will, however, call out your linework, which is scratchy in the first page, and wobbly in the second. Regarding the first issue, remember that each line is drawn once, and only once, regardless of how it turns out. As for the second, recall that what you’re doing here is no different, from what you were doing in earlier line exercises. If your lines could be confident there, they can be confident here, too.

In the rotated boxes exercise, you seem to have forgotten about the initial boxes. Your boxes rotate nicely, so this hasn’t come back to bite you, thankfully, but try to follow the instructions to the letter, just the same. As for the exercise itself, it’s big, and seen through to the end. You’ve even gone the extra length, to apply some lineweight/hatching (albeit, with your wrist, and I notice some reinforcing, too.) The linework is mostly solid other than that, and the boxes snug, and properly drawn through. Nice job, here.

Save for the aforementioned reinforcing issue, and some diverging lines (which we’ll get into in the box challenge), the organic perspective exercise looks good. Your boxes follow the flow line, increasing in size, but maintaining a consistent, shallow foreshortening as they do. As a result, they’ve got a nice flow to them.
