I think too few people draw Míriel - many accuse her of bringing about the Fall of the Noldor. (Personally, I feel the Fall was a mix of everyone's mistakes, including Finwë and Fëanor!). But, like Fëanor, I seriously prefer Míriel to Indis, and I really don't like Finwë for marrying again.
I feel you could have toned down the colours, but it's still great. And yay for giving her silver hair!
