Guys,
can you please help me correct my posture,
below are my current pictures taken a while ago. :|



i really tried my best to stand straight. and yet it looks like my left shoulder is a lil bit higher than my right shoulder.
i am right-handed by the way.
My physical activities are tennis, calisthenics (just started this february, 2011),
jiujitsu.
I've been lifting weights for the past 4+ years.
I work as a software developer 5 days a week, and sit in front of the computer 9 hours per day.
can you please help me? :|
