If I could draw Like ANY Caricature Artist, it would be TOM RICHMOND. Met him a couple of years ago at my FIRST NCN Convention while on the Tram in the Airport in Las Vegas. HE actually RECOGNIZED ME and initiated a conversation. We both rode a cab to the hotel WHICH HE PAID FOR and THAT was my official introduction into the NCN. I was a little nobody, and here was this giant in the industry treating ME like I was an artist on HIS level. I NEVER forgot that, and never will.
Cityscape seems a good subject for murals. But many themes can of course be painted there, for decoration and as a break and escape from looking at cement. This painting by American painter Charles Sheeler, http://EN.WahooArt.com/A55A04/w.nsf/OPRA/BRUE-8DP5GS, would make a good mural as it is as a good painting. The image can be seen as wahooart.com who supplies canvas prints from original art.
