This is my assignment.

Hi, this is my assignment. The side view person is falling forward, :(

These are mine.

Thank you for the lesson. I have a question. I've heard a rule - the darkest lights are lighter than the lightest shadows. However that doesn't work in this example because the lightest tone of the hair is darker than the shadow of the skin. So I am a bit confused.

Very interesting challenge! I tried two values and I must say that sometimes it's not understandable anymore what is depicted on the drawing.

In my opinion visual memory (i.e. memorizing how something is built) and perspective are different things. Correct perspective comes from knowledge and accuracy, but not so much from memory. I really focused on memorizing the structure of the tools and didn't think much about perspective. As it turns out the task was about perspective though.

This is my level 2. It was more fun that level 1.

This was very difficult for me as I am not a technical person. For example in No 1 of the monkey wrench I completely forgot about the screw, lol.

I didn't just 20 but at least something.

I'm late but I still did it.
