Maybe build a little more muscle and shed a little more fat. You know just work on getting your overall body fat % down and you'll be amazing.
For a regular guy you look good, but if you want to be that really hot guy with the 6 pack I think you should work on building a little more muscle and losing a little more fat.
As far as size goes you're perfect. This is why I didn't say you just need to lose fat because if you do that you'll be too skinny, but instead you need to turn the remaining fat you have into muscle so you're just hot hot hot
Didn't you say you lost a bunch of weight? Relax, you are fine... you were probably fine before hand. When people lose weight for body image, they need to take the time to love and appreciate their bodies. More often than not they end up unhappy with the end weight goal, because they never learned to love their bodies and still retained much of their insecurities.
