For film aficionados, the new "3:10 to Yuma" with Russel Crowe was filmed in Gilman - it is very remote and "western" down in the canyons. We took an old road up into the forest, where we saw this "tree spirit". Look closely; he even has teeth! Of course, you would not want to put this into a painting. This is a perfect example of "weird stuff" that you should just leave out... but he was amusing nonetheless.
This second face is a portrait study of the daughter of a friend of mine. I might touch up a few places still, perhaps smooth a few transitions. I have found that painting very young faces is difficult - it seem almost impossible to keep them from looking older! Every time I work on a portrait, though, I learn something, and I'm figuring out which method of "starting" works best for me. For this one, I left the hair in the initial thin wash and kept the background just the white of the canvas for a change.
For economy, I buy large canvas and linen pads - they are about 10 sheets to a pad, and end up costing me less than $2 each sheet. Centurion has a nice oil primed linen that comes in pads, and I believe the pad was only about $16 for the 16x20 size. I usually buy 18x24, so I can cut the sheets down if needed. Check the online art supply places, and you should be able to find them. I think I have a big Fredrix pad also, that is canvas, but has a nice finish to it and paints easily.
