Hello! Grats on clearing up L1! Crits come in quite slowly these days, with people drawing and all. Nevertheless, here's my crit!

On your lines, one thing that is worth mentioning is that your lines need confidence. This improves later on, but its still worth mentioning. In DaB, we focus on confidence over accuracy, even if this would make the line inaccurate, as we can work with an inaccurate line, but not a wobbly one. Unfortunately, due to the wobbling, there's nothing much more I can say in this section.

Ellipses: All ellipses DaB should be drawn through twice ideally, and thrice maximum. In some of your ellipses, especially in the funnels section, are drawn through significantly more than twice. Do take note of this in the future. From what I can see, though, your ellipses are fairly well-shaped. This is excellent, as it shows that your ghosting here is done well. Great job! There's a few jagged edges here and there in your ellipses though, so do remember not to hesitate in your execution. Trust your muscle memory, and execute with confidence. I will say that a large majority of ellipses in the funnels exercise are fairly aligned to the minor axis well, so that deserves kudos.

For the boxes, its important that you should only make 1 attempt on your lines. Even if the line should become inaccurate, treat it as though it were correct and move on. Trying to re-correct it would only serve to draw a viewer's attention to it, which you don't want. Again, your lines, especially in the earlier boxes exercise, are quite wobbly. Try to adjust for that. Your rotated boxes aren't really changing in terms of their vps significantly, making them rotate less. But otherwise, I think these are pretty decent. Organic perspective is also done pretty well imo. Here, I think your lines are at their best. Try to aim for these types of lines. Also, try to draw each box fully. You can use line weight to establish which box is in front of the other.

Overall, I think you've done a pretty decent job here. Aside from your lines, you've more or less achieved the objectives that each exercise set out for you to achieve.
