First I'd like to say that good job on sticking it through and uploading your submissions for critique, even though you think they look bad.

This is my opinion and view on some general fixes, and if anyone else is reading looking looking to review I'd like for their input aswell. I think first you should look into the materials that you are using to submit your assignments, if you don't have any felt pens I think you should just use a reqular pen rather than a pencil. i have two reasons for this the first is because it will make your lines easier to see and just make your drawing look a lot cleaner. The second reason is because they are more permanent that pencil which is one of the important parts of drawbox making sure you can't go back and fix your mistakes and ackowleding those mistakes so you're less likely to do them next time. As for the paper I personally use printer paper because it comes out better in pictures. (Side note I recommend you download and use the Adobe Scan app to take the pictures of your homework they come out much clearer, you certainly don't have too.) Also I saw that for some of the exercises that required 2 pages you only had one and didn't setup the pages correctly by setting them up in 3 scenes on a page like for the Organic Perspective exercise.

What follows is the exercise that I have some comments on based on your submissions(the exercises not included I think were done well):

Ghosted Planes

*  Needs another page

*  Could look to fit planes together a little more so little empty space is left

Table of Ellipses

* Needs another page

* Did very well on this exercise and set up page properly by making the scenes

Ellipses in Planes

* You should use the planes you made form the ghosted planes, if you want rather than making new ones, to draw *ellipses* not circles

* Need 2 full pages

Funnels

* Good amount of funnels

* Ellipses should not cross minor axises and instead mirror on each side

Plotted Perspective

* Review the provided video and steps carefully 

* Page and scenes broken up correctly

Rough Perspective

* Some boxes don't look like they were drawn considering the vanishing poi

* Review the provided video and steps carefully

* Need another page

Rotated Boxes

* Your attempt could have come out better if you had drawn the boxes at the ends of the axis that were intended to be fully rotated boxes

* Review the provided video and steps carefully

Organic Perspective

  • Pages not setup correctly (no scenes)

  • Good attempt

  • Don't need to draw lots of boxes it makes them feel squeezed in and page cluttered

  • Boxes increase in size well

In general I think you should look to follow the steps and videos that Uncomfortable has made more, but i think you made a good attempt.
