I stumbled on this rather artistic graffiti quite by accident. I stopped at Crescent Park in East Providence at lunch, planning to photograph some of the fruit trees that finally decided to bloom. On a whim, I went over the the railing overlooking the Seekonk River, and this was on the wall behind the railing. The texture of the wall was great in itself, but that frog is perfect. I wonder if it's painted on a sticky paper and stuck to the wall, though, because part of the frog's mouth appears to be peeling off in a single sheet. I'll have to check that out the next time I'm there.
Post processing started with a brilliant warm filter in Topaz Adjust. I then adjusted adaptive exposure, regions, contrast, details, adaptive saturation, and color regions. A levels adjustment was added in PSE.
