Many went for the London view - I was one - others, brave ones did the Victorian Conservatory and others the animals. Some of the work can be seen on Facebook here.
It was a cool, gusty but sunny day so I went for the view from the terrace and a quickie of the Market which was on the terrace...in the afternoon to get warm I studied people from above...the foreshortening effect is challenging. Again learnt more than I achieved.
