Before critiquing the actual drawings themselves, I want to talk about taking pictures for submissions. Make sure the camera you're using is at a 90 degree angle from your drawing. Also, shifting the orientation of your photos before posting to a place like Imgur makes it easier for people to view and understand your images. I can't rotate each of the images myself when looking at the Imgur page, so it would just be better if all the images to be oriented in the proper way beforehand.

You've also done multiple iterations on each of the drawings from the demonstrations. That's not a bad thing, but there's two things to consider.

1. In terms of the homework requirements, up to 4 of the plant drawings you submit can be from the lesson 3 demonstrations. The last 4 should be drawn from different references you choose yourself. Here's a collection of some you can choose from. Or you can use your preferred image searching method to find high quality plant images.

2. Submit one drawing of one plant for each of the homework requirements. Doing multiple attempts is good for understanding how to tackle your drawing, but you should focus on submitting your best attempt for each plant on its own page. If you're using high quality drawing paper and are worried about using too many pages, using simple printer paper can help if you aren't already.

If you keep each submission to one drawing on one page, that'll make it easier to take quality pictures as well. The quality of the pictures you've taken does allow for a good amount of zooming in, but in images like the 5th page, each iteration is small enough on the page that zooming in doesn't help as much as if they were bigger drawings dedicated to their own page.

For the branches exercise and throughout your plant drawings, I noticed that you followed the step of drawing past the second ellipse, but you've missed the following step. Here's the relevant part of the lesson page. Don't start at the halfway point where your previous line ended, move back to the previous ellipse to start your next line. Think of it like your drawing a line for each ellipse until the branch is closed properly.

Overall your drawings have good work put into them and they show you're taking time to understand each of the plants from the references. However, you should still work on the portion of the lesson that involves choosing your own plants to draw from reference. I'm marking this submission with a request for revisions because of this. Find 4 other plants you want to try drawing, and post 1 drawing on 1 page. Post the reference images you used alongside each drawing.
