Sketching in Limited Time, Is That Something You Decide?

I think that's, that's like the most because there's so many sketches you follow only on instogram now. And of course, because of the size of your phone, that's what you see. So for me, looking at your books, and i would just imagine that this is the size that you also probably drew them in. I can go over it with a pen in my mentally, or actually with a pen, and try to see how these lines would come about. When we're working in limited time, as urban sketches are, we're always making these creative decisions about where to cut corners,. Is that er?
