Red lights...
Glass reflections... a challenging subject but some really work very well.
Indoor colour...
What was ment to be a 'quick' diversion into Nottingham, the reason was to purchase some very urgent supplies of Winsor & Newton Oil Paint and Winsor & Newton Designers Gouache (bit of traditional airbrush work to do) - Daler Rowney also make a range but not stocked at the place I visited.
A very interesting light, bright but hazy with some foggy patches produced some really good urban subjects, something I really enjoy painting. Standing and sketching in these places is fine so long at you are not in the way of people and really most take little or no interest.
