Like the look overall and think that is a masterful use of colors and textures. However:
Neck of shirt looks a little too "just got off work a need a scotch."
Jacket too snug at chest - looks fine unbuttoned (possibly fits your perfectly with less layers).
I don't understand rolling cuffs on jeans - all devotees aside, it seems like sprezzaturra for sprezzaturras sake.
I also apologize if this is common knowledge since you're somewhat of a lapel celebrity, but what is that curious fishing lure/close pin looking item?
Don't like the belt
Don't like the buttons (look like blue tuxedo studs)
The pants hem look curious - do they have any elastic in them?
Overall, pants and shoes are nice, I agree with criticism on shirt fit.
