Hi I will be doing your lesson 1 review but since this isnt traditionally done there are some things you should do.First no crtz so,eraser,lasso+delete so the experience can be closer to original draw a box lectures.Also its ideal to draw with 0 stabilization so you could replicate drawing on a paper as close as possible tho drawing on the paper and tablet isnt the same because tablet is much more slippery/white board like.Its fine you did this now just keep this things in mind going forward.Also it would be great if you could record your sections for next lessons so others can more clearly see whats going on during the process are you zooming in/out, are you cheating with tool,etc.

So starting off with our lines they mostly look very good.One thing I want to point out is arcing on some longer lines you did.I thinks probably a result of not zooming out.When you are drawing a long line and if you have a small tablet it helps to zoom out a bit.But other than that I think its fine.It kinda takes some time of getting use to drawing lines on tablet and I suggest to play around your stabilization until you find it out.What I did that helped me is tracing other art so I could practice my line work (i did the mostly without ctrz) or downloading sketches online to practice lineart.

Ellipses

So ellipses are also mostly good but I want to talk about stabilization.30% is a bit much in my opinion and when doing ellipses or circles try to keep it around 20% or even lower, play around with it (tho when drawing for DAB do it on 0%).

Boxes

Plotted perspective looks fine.Rough perspective also looks pretty good. Rotated boxes and organic perspective also seem very good.

Very solid submission but keep the thins I wrote in mind.Also this video might helped idk : https://www.youtube.com/watch?v=MzpdGBs0S2w&t=131s .

Next step is lesson 2
