Thanks everyone for your kind comments.
The London USK is a great group of very enthusiastic artists. They are incredibly supportive and friendly, I really look forward to the monthly sketchcrawls.
Potters - I don't usually do anything on that scale; small drawing = minimum detail and quick. However, I mistakenly ordered a large (11 x 14) sketchbook
so now I feel obliged to fill it by scaling up. I can't wait to get back to good old A4.
Clark - sounds like a lost opportunity, come back for a visit!
Maureen - put Greenwich on your bucket list when you next come to London. Its a must-see.
