What Paul said! Is the highlight at the top refelection or on the film? If it's on the film, I would burn it in on the print so it doesn't draw your eye so much. Just IMHO.
I'm all out of sand paper, can I borrow your grain? Wow! this is enormously beautiful! It matters not to me if you burn or leave the sun spot in place, but I do recognize why the others hold that opinion! By the way, I thought at first thought this was a bromoil with that grain. It's exaggerated but juicy just like how bromoil grain goes most of the time.
