Hey, congrats on finishing the first assignment. I can tell you took special care to be extra thorough with the exercises. Full disclosure I am still on the 250 boxes challenge but I believe I can help you. I'm going to recommend you redo some of the exercises but keep in mind I'm not an official critic so following my recommendations is up to you entirely.

Starting off your superimposed lines look consistent and you're making sure to accurately hit your starting point. You seem to be having some issues with wobbling on those really long superimposed lines, probably due to the issues you talked about with being unsure of where your marks are going.

Also, just in case you didn't know, this course requires that for most of these early lessons you are to be making every mark with your whole arm- shoulder and elbow, and not with your wrist. Even when making small marks. I believe the first time you are allowed to use your wrist for fine detail is during the texture exercise in Lesson 2.

You are probably going a bit slow judging by the amount of wobbling, try thinking of drawing superimposed lines with your "whole arm" and moving a bit faster, aiming towards that 2nd point mark. You can practice this by focusing a bit less on whether or not your superimposed line is touching your original line, and instead looking ahead of your line and aiming for your 2nd point. You may see some curving lines or more fraying at the beginning, but the arm motions I'm recommending will see you to improve overall as you develop muscle memory with practice. Otherwise your lines are still very consistent and accurate and show excellent line confidence in your later exercises, so good job.

Your planes show a lot of improvement in your line confidence. You do a great job at centering the intersecting lines. Unfortunately you seemed to have missed the Ellipses in Planes exercise, which has you filling in all those planes you made with ellipses touching each edge. It's a very quick assignment you should finish in a few minutes. Otherwise good job on the planes.

Your ellipses are looking good. You are getting very consistent closeness with other ellipses and you're keeping them fairly uniform. You're making motions with a good deal of confidence which is great. The axis line on your funnels looks like you ghosted them, for this exercise you can use a ruler or straight edge to measure the axis to keep them consistent. They're just a reference point. Not much more to say here, keep incorporating ellipses and funnels in your warmups.

Plotted perspective looks good.

You seem to have missed some instructions on the Rough Perspectives exercise. You are meant to be ghosting every box in that assignment without any perspective lines, and then plotting the parallel lines of your box towards the horizon line to see your inaccuracies and tendencies in your mistakes. You should probably redo this exercise.

You don't seem to be getting rotation on some of your boxes in your Rotated Boxes exercise. It seems this is because you are plotting your boxes to a VP. You are meant to use NO VPs other than the axis you made in the center. Every box is ghosted in this assignment and has different VPs along the axis which allows for rotation. The boxes at the end are simply for rotational reference, not for plotting VPs. I would recommend redoing this exercise. Don't get discouraged though! This exercise is meant to be extremely difficult at our level and it's just an exercise to get us familiar with rotating boxes.

Your Organic Perspective boxes look really good. They're consistently proportional, to my eye at least. You seem to be using a lot of parallel VPs for these boxes, which is totally fine, but try practicing boxes with some more dramatic foreshadowing by using multiple close VPs. You'll have plenty of time to practice this in the 250 box challenge though.

All in all great job! Don't get discouraged on redoing the assignments, it's hard for a lot of us to fully comprehend all the lessons, it gets overwhelming and that makes following instructions very confusing. But that's what the critiques are for! I see a lot of growth and strengths in your exercises. Keep up the good work and don't forget your 50% time!
