I first try with level 1 assignment. The boots were challenging (the laces !!! oO). I find the boot on the right more simplified than the one on the left. I guess I went too much into the details in the one on the left and forgot about simplification.

I tried the level 2. I find it harder to identify the correct light values compared to the shadow values.

I have tried the pear and a custom mushroom. It find this exercice difficult yet very interesting. It's like learning to see the world differently. I find it hard to find the correct values and to know where this value should start and end.
