Hi Stonechild! I'm Piapal and I'll be reviewing your work!

First of all, congratulations on finishing the first Drawabox lesson!

Lines

Your lines are not wobbly, which is remarkable and good! They look steady, maybe not 100% straight in the Superimposed lines exercise, in which I can sense them curving a bit, but it's not critical. I believe that you will improve this with practice and thus gaining more confidence in your line-making. I want to congratulate you on having almost no fraying beginnings, which means, that you have been carefully placing your pen at the beginning of each line, and then executing the action. It's very important that you keep doing this, since patience and concentration is Drawabox' core. Remember to do this while drawing Ellipses, too!

Ghosted Lines: many of them accurately land on both dots, which is great, and they look straight too!!! Which is great, keep that up!

Planes: All the lines look straight and accurate. Good job!

Ellipses

Table of ellipses: I can see that you've struggled with this exercise, because many of them don't fit in the table, they're smaller than the table itself in the first page that you've handed in. But in the second one, I can already see improvement!! Which is great, and means that's a calculation error and thus avoidable if you ghost your ellipses enough times until you feel confident enough to execute the action. Take your time, gain confidence, and then, draw the ellipse. I'll request a revision from that one exercise.

However, in the planes exercise, maybe 3 ellipses are either smaller or bigger that the plane, the rest of them look fine, so I guess that it is a matter of practice.

I can also see that you're trying to draw over them two times, which is what's asked for and therefore great, however I could also see that you haven't done that in a few ellipses. So I'd encourage you on keeping that in mind: redraw the ellipses 2 times and don't rush trough them. I can also sense that they've been done through engaging your shoulder so congrats on that too.

Same with the Funnels exercise: the volume of the ellipses looks conserved in each of them and they're also well bunched up together.

All in all: keep working on ghosting before drawing the ellipses and concentrate on making them fit in the table! You could make warm-ups with that.

Boxes

The first one looks great. However, I can see that in the second exercise where you cannot use a ruler, you've been going over the boxes. Restrain from doing that. I know it's hard because we hate when we do mistakes... but try to restrain from doing that because one of Drawabox rules is to not go over the lines you make. Instead, ghost the lines as longer as you need, in order to execute confident and straight lines. A tip: when I ghost the lines for a box, I tend to extend my arm in direction to the Vanishing Point a few times to train my arm muscles. Then, I execute the action, drawing the line in the direction of the VP but obviously not all the way through. This helps me to nail the perspective, yet it's not perfect all the times and that's okay!

In my opinion, you've done a great job in the Rotated Box exercise. You've left a bit more space between each box in the left side compared to the right side. Therefore, the boxes doesn't seem to rotate that much. I don't know if you've rushed in that part too, since you could have reduced that space and put them closer.

And sometimes, the set of parallel lines don't match the VP. This is expected because it's one of the first exercises in which you confront 3 VP's. In your warm-ups, I'd redo a few boxes and try to match the set of parallel lines to the VP's without using a ruler. Once done, I'd use a ruler to check if the lines meet the VP's, like you did in the Rough Perspective exercise.

The Organic Perspective exercise looks great too, even though a few sets of parallel lines don't match the VP¡'s they are supposed to meet at. (Which is expected, and I still encourage you to warm up practicing 3 point perspective to become better at that. The 250 box challenge will indeed help, and aid you with the practice that you require.)

All in all you've done a great job. Keep up with the good work!!
