What darling girls. I especially like the color in the water one. Watch your skin tone transitions. Make sure nothing pops out, like a too-sharp highlight. When working with children, I usually have a large blowup of a photo next to them in the same pose. I refer to the photo as the good kid and the model as the bad kid, giggles all around. The child can move a lot but you can grab the color and draw the form from the photo. Check out the posting I sent to Geri Comicz at
