I don't think the tie is cheap-looking or unfit for wearing, but if I had a choice of Brioni ties, I would probably choose one with a more subdued pattern. The biggest problem with your shirt is its more casual pattern. Swapping that shirt out for a solid would significantly improve the combination.
That's a loud pattern? The hell? It's not as boring as a solid, but it's more than subdued enough for just about anything outside a funeral.
It's a nice tie. I would swap out the shirt for something solid, but that tie and the suit are fine. The shirt's fine too, but the scale of the checkish part of the tie pattern and that of the shirt are too close. White or blue, though I think I would prefer white.
