While the hand might be more authentic squished together a bit more, the court herald in me is happy to see a hand that I can READ, even in the usually less than optimal lighting without having to fumble with a script or other aid!

I think it looks absolutely lovely, and I agree that the emblazon is spot-on (though I did 'cheat' and look at the original paperwork since I have that available). It's an exact match, actually - the stag's head is better done in this version, though! Good Job!
