On my monitor, her face looks a little splotchy. Parts of it look a little too light and parts of it look a little reddish. It may be because of the 512x512 texture limit. I'm not sure. Also it looks like there's a little discoloration under her left eye. It's hard to make constructive suggestions because I don't have P5 yet (I'm on a Mac) and I haven't personally made face textures. All I can do is point out what it looks like on a monitor with a different gamma setting. ON the whole, nice work and it definately looks like you're getting closer.

Before they made me they broke the mold!
