Here are my pec inventions. Feedback would be much appreciated.

Here are my robo beans. Tried to keep the proportions between the torso and pelvis boxes fairly accurate, with varying degrees of success. The twisting poses caused me the most headaches I think, especially in poses where both front and back plane seemed to be visible at the same time... Great perspective practise! Anyway, I would love to get some feedback on these, especially pin pointing any reoccuring errors/misinterpretations.

Here are my attempts. I took a lot longer than five minutes, although the last two pages I really tried going faster and not be as stressed out about accuracy to get more flow. I have a problem keeping the drawings inside the page even though I make an envelope for the drawing first. I also have a bad habit of erasing way too much and making "hairy" lines. Working faster helped a bit with the line confidence. Any other thoughts or advice for me?

Here are some of my mushrooms. Sorry about the lighting in the photo... Clearly need to get a better desk lamp for my drawing space :D

Made another attempt at level 2 after watching Stan's demo. Spent way more time on the layin this time around.

My attempt at level 2.

Here is my attempt at level 1. Found it difficult to fill in the light values consistently. Used 4B, 2B, HB and 2H graphite pencils. Feel like I made the midtones too similiar to the reflected lights. Maybe I should have switched the 4B to a 6B for the darkest shadows and pressed harder with the 2B for the lighter shadows? Or maybe just press lighter with the HB pencil for the midtones? Anyways, now to draw some more fruits before giving level 2 a try!
