Countdown to someone in the threads saying "collar gap" starts here... but personally, I've found it fairly worthless to comment on fit in casually-taken/posed snaps for SF and will instead comment solely on the lovely colours/combination. Nice to have you posting in the thread; it's all too rare!
Don't know what it is, but I'm not quite feeling this one. Might be the shade of orange in the tie seems a little too bright/vivid for the brown of the jacket? A darker/muddier/burnt orange might jive better?
Colours are nice and I especially like the shirt. I must admit not liking single logo ties like this (same goes for the 7 ties by the guy with the vowels-and-zs name). I figure crests look best when placed all over the tie, not in isolation. But I tend to like my ties to be either super-loud/flashy (and ugly, depending on your POV), or super-conservative/traditional, with very little in between. Your tie very much falls in that middle area of trying to be both soberly conservative and have a flashy aspect. I'm not sure that's an entirely feasible synthesis, to be honest, but that's a wider question I guess. I'd actually put the shoulder stitching on this suit in the same category of trying to send out two very different messages at the same time: sober business suit, but unnecessary decorative stitching (it doesn't look like part of the construction on that particular shoulder type), but obviously that's a much more subtle example and not as noticeable.
