First of all, sorry for the huge picture.
Is there anything it clashes with? Obviously, I didn't spot anything on that front. I suppose the blue in the square picks up on the blue shirt, but it's not a big thing.
I don't see any clashes!
I would have gone lighter if you had one though. I also think that the tie and the jacket look too similar in tone over there, but that might just be the image.
I like it, but was just being slightly critical!
