Here is a Mural I did for my son Arthur's room. It was painted at around 8000 pixels wide at 150 dpi, and the end result was a 4'X12' vinyl wall print. It was a fun project that I hacked away at over a period of months, mostly because of the large size. Soon he will look much older than that toddler I painted him as.
These are a couple of studies I knocked out this afternoon. The first is a portrait photo study from a photo in the Atlantic In Focus section of the Atlantic online publication. The second is a study of the late afternoon lighting in my living room, which changed rapidly as the sun went down. I will have to try another later with the artificial light to get a bit more accurate and detailed.
