Hey there MardukMishima, congrats on finishing lesson 1!

I'm Miu and i'll do my best at giving a community critique. If you feel like my critique is lacking/unfair, feel free to head over to discord and ask for someone else to look over it as well.

Lines:

Your "Superimposed Lines" came out great. Nice, confident lines with a well defined starting point and only fraying on one end.

Same for the "Ghosted Lines". Prioritizing confidence over accuracy is key, as accuracy will come with time and mileage.

The "Ghosted Planes" put this into practice and here you continued with your confident lines and it seems like your accuracy is already improving. Good Job!

A tiny nit-pick i have with this is that you mostly went with orthogonal planes/rectangles. If you do this exercise as warmup in the future try to incorporate some more slanted planes/rectangles with a greater variance in corner angles.

Ellipses:

Your confidence carries over into the "Table Of Ellipses". Your ellipses are followed trough twice, while aiming to keep them within the borders and slightly touching each other. You also experimented with a wide range of sizes and tilts, without sacrificing your confidence and follow-through.

In the "Ellipses In Planes" the same thing applies, confident, smooth ellipese that fit more or less snugly into the planes.

I noticed that you drew these through three times, here and there more like 3.5 times. Try to keep the follow-through to either 2 or 3 in the future, as the ultimate end goal is to draw smooth ellipses in one line. However don't worry to much about this, you still have plenty of time to use these exercises as warmup and improve over time.

Same thing applies for the "Funnels". Great confidence with smooth lines, but especially in the first two funnels the ellipses aren't touching. And the out-most ellipses of the first funnel seem to be "floating". The goal of this exercise is to align the ellipses along the minor axis, while being confined to the funnel shape. Other than that, i really like, that you continually widened the ellipses as you moved further from the center.

Boxes:

"Plotted Perspective" looks great with clean hatching.

In the "Rough Perspective" exercise you continue to prioritize confidence, which is great. Using dots to estimate the boxes and then confidently executing the lines. Maybe a note on the dots, as i haven't mentioned it yet. Try to keep your dots as small as possible. Big dots can leave you with a greater margin of error, while technically "hitting" the target.

There are a couple of boxes that look slightly slanted, keep in mind, that the width lines sould be parallel to the horizon, while the height should be perpendicular. Overall a solid job as the extended lines are mostly close to the vanishing point.

For the "Rotated Boxes" you kept the rotations pretty tame. And while you kept the gaps between the boxes in front consistend, on the back the gaps vary a lot, especially noticable in the right upper corner. The boxes on the lower right vanish in the wrong direction in the horizontal vp direction (I hope i got across what i mean by that, it's hard to describe). But thats me being overly nit-picky and more of an observation than an actual critique. It's a hard exercise and i think you did a solid job, with room for improvement, but the 250 box challenge will do just that.

One kinda off topic note here: try to keep your hatching lines smooth and confident as well (Yes, that means ghosting them.). They are a little all over the place and wobbly here.

Last but not least "Organic Perspective". Looks really good as well, nice progression from big to small boxes and a lot of different orientations. One thing, although most of your lines are really confident and pretty accurate, you seem to have some lines where you wanted to correct the lines with another one on top. I know it's tempting but try not to do this.

All in all, you did a good job with these exercises. Sure there is some room for improvement, but your line confidence is pretty solid and it seems like you have a basic understanding of perspective already, so i'm gonna mark your submission as complete.

Good luck on the 250 box challenge, keep up the good work!
