Thank you so so much for your amazing feedback! I really can't stress how much I appreciate the time and effort you put into it.

I've ordered the recommended fineliners which have arrived a couple of days ago, so I was already able to try them in some 50% sketches and just outside this course to get a good feel for them.

Also I'll definitely focus much more on not going over lines multiple times, such as seen in the ellipses. That is, unfortunately, a bad habit I've picked up on prior.

About the converging lines where there shouldn't be any, I'll just do those in some warm ups to try to get a better feeling for them, while also of course giving it some extra focus.

Again, I really can't put into words how thankful I am for your response! Thank you so much for your motivating words too ^^

I wish you the best, take care ^w^
