You sound very slim, but I like that. As long as you're not anorexic, there isn't a problem. Always bear in mind you'll most likely put on some weight as you get older. Most people wish they could lose it. You have a head start!
My personal feeling? You are pretty perfect, at the top end of my ideal height range.

Wow, I'm 5'3 and 128 lbs. I think that as long as you are not starving yourself for your weight then you should be fine, but a little more weight would do you some good. This is probably just a (don't hate on me for this) phase that you think you are too skinny. Some days I feel like I'm fat as hell, and other days I feel like I'm sex on legs. The curves part doesn't really matter, what matters is that you are not just skin and bones.
