I don't feel that it's a particularly harmonious rig but I give you an A for not boring me to death.

I like having one discordant note but not two,  so for me,  I would choose either the shirt or the square but not both.

Your tailor's choice of thread color for the buttonholes is somewhat distracting but I like the color and scale of the fabric's pattern.

Gentlemen - thanks for the replies.  This isn't my suit it is just a picture that has me thinking about what I might do.  FNB, I agree with your assessment, this is a casual suit not a real work suit.  I also would agree that the thread on the buttonholes is less than perfect but I am not sure what would work better--ideas?  The pocket square, tie and shirt combo are quite dissonant.  I like the suit and the shirt fabric but the rest.  FNB would love to see your fabric/suit when it is complete sounds like it would be great early winter party circuit stuff.  A somewhat casual environment would be my context as well.
