Firstly, hello and welcome to the forum!
I myself haven't seen any of the latest Galadhrim models in person yet but I've heard a few people say they think the moulding is sloppier than the majority of minis. It would be great to see some pics of your painting and the members around here will be more than helpful in helping you to improve your skills, just post them up in the WIP section or your gallery when you're ready.
As for painting eyes and hair, these are the trickiest parts of a model for any painter, especially the eyes. The following article is probably the best guide for painting faces and eyes -
kb.php?a=182. However it doesn't cover hair. For hair, the easiest way is to use the drybrushing technique across all of the hair and it will pick out the highest points of the hair and highlight them. When you start to get more advanced and are willing to take more time painting you can highlight the hair picking out each strand seperately, but it does take much more time and will require a steady hand (as will painting eyes). There are lots of painting articles in the Tomes of Wisdom, each covering different ways of painting hair though, so feel free to browse them all and find a technique that suits you.
Hope that's of some use to you, again, welcome!
