Looking through it again, I am very impressed by his robots and by his obvious adoption of things he learned from Giffen, but subtly unsettled by his faces and poor body language. I don't want to be dismissive of him, especially as he is still working and I find him to be a very good artist in a lot of ways. But I think putting him besides Giffen says it all -- his stuff is, for some reason, motionless. It simply doesn't bounce. One of his best tricks is to freeze a motion at the best moment, and some of his finest work has that sports-photography feel of a perfect instant frozen in time.
People keep mentioning L3W, I suppose I shall read it.
