Looking good mate!
If the David Beckham look is what your after...well sorry... Too late! You already have a FAR superior physique to his
Nice and lean... As winger said post up your diet and people should be able to help you add a bit more mass on your frame. From a purely critical point of view I would say your Lats could use some work. From the back shot you posted I can see that if they were to fill out a little it would give you a much better overall look and add to your V-shape. Although having said that I can't see too well since you have a vest on
Can't really tell how your chest is doing either due to the vest.
Anyways... Looking fantastic dude. Keep up the good work.
