P90X Day 28 comparison

The P90X program suggests taking pictures on Day 28 to compare with Day -1.  While these pictures look kind of stupid since I'm trying to maintain good posture, I think they should some subtle improvement.  My body composition scale tells me I've lost 3 lbs in these four weeks, all of them fat.  I'd like to lose 1-1.5lbs of fat per week so I'm off target, but not by too much.

I think I have a little more definition in my torso, front and back, but you can judge for yourself.

I've still got a ways to go, but I'm fairly pleased with my progress to date.
