Hi, Fishb0y! Just thought I'd come in to critique for you!

First off, your superimposed lines look really good! The way the lines are made are smooth and you kept the starting points all together at one place. You also did a good job executing your ghosted lines! While there are some that don't seem to reach the endpoint, they remain very confident. The same goes for your ghosted planes; the lines are smooth and straight, but some miss their endpoints. My suggestion is to take a bit more time to "ghost" your lines so you'll be able to hit the endpoints accurately.

You performed pretty well with the ellipses, however, I see some wobbliness present. I also see some of them not making contact with the edges in the ghosted planes exercise. Overall, I think you still did really well with the ellipses section, especially the funnels.

Now, as for the boxes, a few of them in the rough perspective exercises are distorted. Your main focus here for this exercise is to converge your lines that go towards the vanishing point. The rest should be relatively parallel to each other. To make this easier, you can plot the dots first so you can tell where to draw your lines. Moving that aside, your rotated boxes look fantastic and I like the way how you almost rotated them perfectly! And you did a good job with the organic perspective boxes as well. You should try to make the boxes that are close to you a lot bigger to emphasize their distance.

In conclusion, my advice is to add the ellipses to your warm-ups, although, as first priority since it's better to practice lines and boxes as well. You should remember to always use your shoulder and "lock" your wrist and elbow in place as this will allow you to create confident lines as you draw. You've put in a lot of effort to these exercises and I can assure that you're good enough to move foward to the 250 boxes challenge.
