definately noticable improvements. The tan also makes a bg difference, but your chest and shoulders look much better in the second set of pics, and your back looks alot better aswell.

Keep it up, just keep training hard on everything, eat for size, as if you try and cut you wont have a great deal of muscle to display, so id bulk for afew years first. Keep the diet pretty clean and you wont put on much fat.

Good luck, nice to have you onboard
