Can't say I've ever seen the puffy pics - but, to be fair, all photography is about light and angles, and unless you have a pro taking them, you're gonna get unflattering ones *speaks from bitter experience* :\

In my experience, there's a thickening of the waistline and broadening of the shoulders that comes with healthy maturity [perhaps witnessed in whatever that spn episode was that Jensen wandered about in a towel, compared with his performance as 'Monty Cora' in Dark Angel]. Jensen's got a man's build now - and I very much approve. ^^
