Anyone got tips I literally can’t get the structure or see the shoe correctly

These were both after the demo but I’m honestly struggling. The snail one I was able to complete but, the boots just had me so frustrated any tips?

Before and after demos.

Post critique, 3rd effort, trying to make more deliberate confident lines. Takes a lot of patience to make sure you're deciding in advance C S or I and then "ghost it" before you commit.

Snail Before and After Demo

My boots and snail before the demo. Boots were challenging, especially the laces.. I ended up simply adding floating curves for the visual "emotion" it provides For the snail I added texture for the fun of it :P This is a big improvement for me, I really enjoyed the process of working on these exercices :D

My snails and boots before and after the demos. The laces were a doozy, and I made the mistake of swapping to a darker pencil on that second pair of boots. Any advice is welcome!
