Fingolfin and Luthien II are authentic Tolkien designs (I have them on my dad's slipcover to the Silmarillion.) As for the rest, I don't think that they are authentic designs, but they remain strongly in keeping with the other designs, authentic or not. Great job!
(I would guess that the ones neither marked -movie- or that I picked out come from some other source that I haven't seen: either legit Tolkien, or your own imagination?)
