One too many bits of fun there, I think, Don. I like it, but I think with the jacket done up it would tie together better (and look more flattering) - is the jacket a bit small to fasten comfortably? It's lovely anyway. I think with all that going on I'd go down a notch in colour on the trousers, but you're certainly cutting a dash.
One specific small change though: the tie and PS are both quite orange - as is that fierce overcheck. They're all great, but too much together. Changing even just the PS to something based on greens/browns or even navy, in a dull shade, would just soften the edge off this. I think that tie and PS should always be of different colour families, or at least different ones dominating.
