I think you look great - well and healthy!
I must admit, I agree with Mixxy on this one. It's the contrast with the 'old' you rather than people's ideas about the 'new' you. People who knew me fat often say I look too thin, ill, tired etc. People who have only ever known me thinner never say that. I always think that it isn't really surprising. It is taking me a long time to get my head around this, other people must surely be struggling with it too.
