I don't mind the stuff from being too low other than the stuff directly in line with the legs. I have run into the problem of being "too low" myself--I am not sure there is much to do other than picking a better spot. If you raised up I don't think you would have as nice a background...
Wicked yawning pose Bob!! I'm sure you could have gotten an inch or so higher and still gotten away with a nice BG. I like the early morning (?) light you got.
Great pose with great light. Sharp and well exposed. I do think you were to low on this oof fg does distract fo me. Maybe crop some off the bottom. What do you think
