An Ageless Question

Recently, I've been wondering about my style, and although it hasn't solidified yet, I think I managed to establish a certain 'feel' to my pieces. Realizing I'm painting mostly Aes Sedai, I thought that I might as well perfect the ageless face. Since starting digital painting, I've finished four characters that are supposed to be ageless - Verin Mathwin, Siuan Sanche, Bera Harkin, and Kiruna Nachiman. So far, the nearest to the ageless look seems to be Siuan Sanche, which kinda makes me not so satisfied.

So I browsed through different approaches to digital painting, some are rough, while others are extremely polished, so I settled for something in between. Having a piece and a character in mind, I started a new style, with 'agelessness' in mind. Here's what I came up with:

My bf actually helped point out that (in photos of ageless women we browsed online),

the agelessness had something to do with the eyes - they were creased, sad, and almost droopy, while the rest of the face was unaffected. I pointed out that botox helps, and even plastic surgery - causing that tiny curl in the lip, a little cat-like in overdone cases. We both agreed that the cheeks were a little too emphasized and rounded.

My perception may be a little distorted, but I do think this unfinished portrait somehow hits near the mark. I sure do hope I can repeat it, as I suck when it comes to repeating works (hence I did not become a comic book artist). As only one of four characters in a piece I'm planning, I'm a tad bit scared to finish it.
