Holy wow!
The first time the picture started fading to Valinor and the sheen around Taniquetil (presumably? Or just a tall mountain?) started lighting up around Sauron, it looked super cool and phantasmagorical. The background transitions look fantastic!
But my first thought upon return to a more rational state of mind was that I'm glad I'm not the only one testing the limits of how elaborate this can get.
Sauron gets an Eye! :-D And his bat crown looks fabulous. I can see why you redid Finrod, but I feel like this picture is a bit less like him. If I saw it without any context, I would probably start guessing female characters first. Though I think that as I am looking more at him he's starting to grow on me.
