Great job completing part 1 of Lesson 1 Mariel!

I'll critique in the order that the images appear on Imgur.

Ghosted planes looks good. Your lines are a bit wobbly overall. Remember to focus on the end points, and not to worry about the in-between, other than getting a powerful stroke through your shoulders.

Rough perspective could use a couple more boxes, and your lines are wobbly here as well, especially for shorter lines. A couple things could be causing this, but I suspect that it's due to correcting yourself and a lack of ghosting here. You first concern should be planning you points, and after you've done that, you're only concern is making a straight mark. Wobbly lines are significantly less likely if you've done those first two steps correctly.

Superimposed lines looks pretty good as well. I like the red pen, but I'd stick to dark colors. There's considerable fraying at the beginning of your lines. This can be avoided by properly placing your pen before each line. Trying slowing down if that helps. Long lines have this problem more pronounced, which may be an effect of lapsed attention.

Ghosted lines is a bit hard to make out because of the image quality and the red pen, but it looks good as well. I looks like you second guessed yourself a couple times which is no good. I like the line length variety.

Ghosted planes looks great. Slight wobble but overall it seems like you put a lot of thought into each line. The planes themselves look very pleasing as a result.

Table of eclipses looks good as well. The eclipses are touching another consistently, and you've ghosted through them the proper amount of times, for the most part.

Funnels is also good. You have some inconsistences in terms of shape of the eclipse, but the confidence in your line making really stands out.

Ghosted eclipses looks great. Thank you for using another color! Most eclipses touch each edge, even with the variety in plane shape.

Plotted perspective looks great. Good diversity in position, perhaps some more in size.

Organic perspective has issues related to planning and linemaking. There's considerable wobble in your lines here. It doesn't look like you negotiated your corners (by placing prospective points) here much either, which indicated a lack of planning. This haste may have led you to be more conscious of how you made your lines, which hence the wobbling, nervous line-making.

Rough perspective suffers from much of the same issues listed above. Ghosting is key. Skipping these steps will hurt your line-making. Thank you for using another color while checking your work.

Rotated boxes also suffers from the same issues. Throughout the exercise I see poorly placed corners, which subsequently harmed the box. Especially towards the most rotated boxes, which also suffer from poor line-making. Even the smallest lines must be drawn form the shoulders and ghosted.

Good job on completing part 1 Mariel!
