Woha, what a nice review, thank you so much for all the details you pointed.

I'm not gona lie, before sending to you I did quite more ellipses to try to improve on that, I'm sending the one that looks more confident, I had to speed up as you said, but instead they were quite innacuarate and couldn't hold up with diagonal cuadrants. I think that I improved the most on the rough perspective, ellipses are really hard, I mean I can do really good ellipses but only if I do a big ones, when I'm forced to draw little ones, my aim gets worse
