Thank you @cryptoandcoffee for your kind comments - I think I've always taken a sketch book on trips. I don't try to capture the essence of a place, or the main attractions. Just things that look interesting and have good form, shadow and contrast. The last drawing is an abstraction of a museum installation, where I added patterning from pottery I saw on display. so some drawings are completely abstract. Last year I visited Portugal and had more time to sketch. You can see it here https://steemit.com/travel/@mrsomebody/sketchtravel-in-portugal
