There's clearly been lots of struggle here, it's visible from the drawings. I had to erase a lot as many lines confuse me, would emphasize the lines in the wrong places, I had to take more time than envisaged by the reel, then I would get bogged down in detail etc etc. I think I committed every mistake you have warned about in the lectures.
In any case, I have found it incredibly beneficial and I think I might repeat the reels to see if I can progress more. So, for that, if you would have any specific advice on what I can focus to improve this time around, it would be much appreciated. My impression is I should focus more on the line fluidity and proportions. I realized I can't focus on more than 1 or two things at any time.
