I should also mention that I kept a small journal while abroad; I guess I can share some of those sketches too. My preference is to draw from life, but when there just isn't any time, I take notation, visual and written, snap a photo if circumstances allow, and later use these fragments to construct larger diaries. It's time consuming and sometimes quite challenging, but ultimately well worth it. It's a good system.
So that's what you'll be seeing; these tiny sketches are my notes.
