I think you look great! I'm 5'7 too and am at 192 right now. I hope I look as good as you do when I get in the 180s (hopefully soon) -- I'm shooting for 160 as well. Can't wait to see your end pictures! Keep up the great work!
You carry your weight well. I can never guess how much people should loose..plus it's all relative. All I can say is good luck on you rest of your journey. Your doing great!
ps how much have you lost so far?
