These next two are just pencil sketches.  The one on the left is a church we saw in La Jolla, while wandering around town.  The one on the right I call "old man Ryan" - it's a drawing of my nephew in his big winter coat, but for some reason every time I try to draw one of the kids' faces they always end up looking a lot older than they actually are.  I think it might be that I'm not drawing their faces wide enough for kid proportions - but I'm not sure.
This last one is a pencil sketch of a tortoise we saw at the San Diego zoo - the sketch doesn't get across the size of this thing, though.  He was big enough that I could have climbed on his back and taken a ride around his enclosure - my feet might have touched the ground, but not by much.
