The reference I used for this was shot outdoors, meaning skin tones could be different, but here they are really quite warm. Doing a portrait from a photo reference without an opportunity to see the actual subject is not optimal of course, but in the case of these foster kids I've made an exception. If I was doing a commission, I would need the subject to sit in my studio, under controlled-temperature lighting, where I would do a preliminary color sketch and shoot perhaps 20 to 50 reference photos. I'd also try to have more than one sitting if possible to at least start the final portrait. That isn't always possible when you're painting someone whose time is limited, but the first reference sitting is a must. At about 7 inches the head in this 12x16 portrait is near life-size.
As soon as this dries sufficiently, I'll ship it to the Heart Gallery that will display it.
