My only note is you should really move the buckler to the guys hand. A buckler is not worn on the arm like a shield it is center gripped.
Yes, thanks Dr Z. I know that

It's mainly used to punch - an offensive weapon rather than an out-and-out defensive shield.
But as with the mixed armour, whilst it may not be right, I just like the effect it gives, as if strapped onto the forearm.
I'm really not a purist when it comes to historical accuracy, I'm afraid
