Firstly, you're going to be twenty in-game feet away from everything, and secondly, it's all going to be in motion. It'll look better, with not much point making it higher-res.
Secondly, I'm with Gibbons. Slap on a specularity mask or something - eyeballs need moisture to look alive, and eyes pull a lot of weight in the realism of your character as a whole.
You all need to play the orignials again and realise how much detail you were filling in with your imagination. But hey, if that's what you need from a game, just play N&T in 800x600. With scanlines. I want my "Classic Mode" option!
