I've made some Level 1 and level 2 drawings after watching th livestream and both demos. Would love some feedback :)

Made some circles

those are a few attempts at level 2

i've tried to draw panda bears from imagination after watching the demo

the last one is from imagination Im planing on returning on this specific project every now and then to enhance my drawing from imagination abbilities

some more attempts with level 1

Hope the Pictures look clear enough to see what i've drawn

i've tried to analyse the Lines.

My Key Takeaway ( hopefully right becouse english isn't my first language) The Lines need to represent, what im trying to draw. Is this form best represented by a dark thin line, do I indigate this Shadow with big soft lines, does the line represent the texture of the form etc. How I represent something with a line is Up to interpretation and the Type of drawing that im doing ( it doesnt have to look 100% like reality but close enough). Please correct me or ad something in case I got something wrong or forgott something becouse I want to be 100% sure that i understood it.
