This is a good example of the kind of thing I do on a daily basis. If I am not working on a serious project, I mostly sit around and do these kind of basic perspective prac sheets.
It might not look like much, but these sheets are very good at conditioning you to make very tight lines and very fine measurements.
What you see here is simply a look into my process and what it is taking for me to become a good artist.
