You've hit a rich seam of form lately it seems, H.
I can't say I like the design of those Haradrim (they look like they're from some kind of Middle Earth Mad Max movie), but your treatment of them is magnificent.
I really like them. Very remote and exotic.
I do have a problem with some of the decisions Peter Jackson made about human races under the sway of Sauron; they were not to be based on any recogniceable culture of our age. This is of course something GW picked up on.
The stories that Tolkien wrote is a a mythicak pre-history with a distinct Nort Western European point of view. I don't find the stories racist even if xenophobia cetainly is expressed in the stories.
It is quite obvious that corsairs of Umbar took inspiration fron the barbary states of North Africa, the haradrim from moors and saracens of North Africa and the Middle East, and the tall, black skinned men are sub-Saharan Africans.
You've got to ask yourself what's more offensive: to be depicted as fighting for the wrong side or to be not be represented in any way at all.
