So I redraw one of the photos taking into consideration the points in the video. One of my mistakes was that I focused a lot on the contour and I tried to do perfect lines. Also, I stop worrying about proportions and focused in the connections (I did a few mistakes with the arms but I'm still satisfied with the result)

So here are my attempts. I'm not sure if I'm oversimplifying but and trying my best to use only SCI lines and ignore small details and bumps

Here is my submission. I tried my best to simplify the shapes created by the lightning. The most difficult part was trying to get the right angles and proportions of the light and shadow shapes inside the pear.
