Ken,
I love your shots. For those of us that are curious about the lighting set upobviouslythe flash wasn't shoe mounted since it was shot through/into and umbrella so I was curious if it was fired ETTL using the ST-E2? or did you manually set the flash exposure and use another wireless trigger? If I had to make any kind of comment on the composition I would have prefered a few of the shots (specifically shots 2, 3 & 4) to be a little more eye level with the subject. That being said shot 5 I actually like the above angle shot it works with the lighting. Your shots are still amazing it's only a minor comment.
