Hey, great tattoos, rock!
My comments must come with a caveat, in that I am also the world's suckiest poser, heading for my first comp (and am trying to teach myself in my basement with precariously-balanced mirrors). However, to that end, I have been downloading every photo I could find and sucking up advice from every one of the few pros I know.
General comment: remember your legs! They are just hanging there most times. One guy told me to not only
spike the leg, but sort of "pull" it as though you were trying to "drag" the foot along the floor. Also, you could maybe "sit" on your poses a bit more, particularly since you're tall. Would help especially with the ab shot. And the back shots. And, er, the gluteus. I don't think you are squeezing your gluteus. It's the high-protein diet... we forget that... pretend you gotta go gotta go! recall the good old days...
Front relaxed, your shoulders look somewhat hunched, giving you more of a corvine air than the doorlike breadth one wants. Also gives the impression that you're "defensive".
Side tri: drop your forward shoulder a tad I think. Also, another tip someone gave me (a guy who won a junior BB champ a few years back) and which
seems to help: instead of grabbing whole hand, grab just the first two fingers of your hand. Then your arm isn't so squashed, and it opens out the bod a bit more, as well as giving more leeway to display, in the manner of the peacock you impersonate.
Side chest, you're totally wasting your legs. Get your foot up right chummy with your other foot, and flex those quads!
Not sure, since of course I haven't seen you otherwise, but in your bi shots, front and back, your elbows seem kind of low. Might you get better "volume" hiking them up a bit? Interesting... notice in the back bi shot that your tattoos coordinate very nicely with the wallpaper border!
The thumbs in your rear lat seem somewhat inartistic. And in your most muscular, your arms that way, er, hide all the muscles. Might wanna try some of the variations on that pose, specially since you seem to have a good bit of upper bod going on. The big weak point that leaps out to my naive eye is your calves, and a general tendency to hunch your shoulders.
All bearing in mind, as I say, that though I am verbose and terribly research-oriented, I am not so experienced in the practical.
