Am I Really Shrinking?

I've received many comments from people recently saying "You've lost weight!" I especially hear this from people I haven't seen in a couple months. I know my shirts feel looser than before, but have I really lost? Since I haven't weighed myself in ages, I thought I'd use pictures to tell the whole tale.

So here are three pictures, one from two years ago, one from March 2008 when I first arrived here, and one from this month. Tell me, do you think I've gotten smaller? And if so, where do you notice the biggest change? If there is noticeable weight loss, I wonder if it's due to my new Japanese lifestyle, or if it's just a natural occurrence from some other reason. Please either comment here or on my Facebook wall.

I have my own opinion, but I won't share it yet, just to see what others think first. But I will say one thing, holy crap I've tanned a lot! Look at that pasty white boy in the middle! I guess walking around in the sun for five months will do that to you ^_^
