Excellent!
Just a couple of things... for the arms you have called Fasham Nairn - the black and silver are in the wrong places (as you suspect). It should be 1 and 4 = black and 2 and 3 = silver.
Also - you have the Gryphon on a blue background - this background was light coloured and that above the grailed edge was dark coloured.
The crest could well be exactly right - but as I said before it was so tiny that the detail was not clear.
By the way, the motto on the crest was VIRTUE ET HONORE.
