These are my level 1 drawings. I had fun drawing them and using only CSI lines which definitely helped me in making every single line intentional and clean!

So, this one frustrated me quite a bit. For the first two I just couldn't stop adding unnecessary details. I also couldn't bring myself to draw with my shoulder or my elbow. I almost gave up, but then I decided to draw on bigger paper instead of A4. I tried to be looser with my lines and simplify more, but I'm not sure if you can tell. I'm still rather happy with the last ones.

Here are my attempts. For some reason I couldn't get a good photo of the second one, sorry. I also got frustrated while drawing. I don't like the shapes of the shadows on the pear and with the guy I had trouble making the shadows different enough values so I kind of rushed it at the end. :/
