Well, I never play with Galadhrim archers. The woodelves are better for the shooting: fire can't be returned due to the 12" Enchanted Cloaks. And you don't need that much WE boxes to get the much archers: they start with handweapons and throwing weapons, and you can give them Longbows. So you could put in 4 WE archers in the 4 front rows, and other WE's in the back. This way you can easily get more companies 'without' losing the WYSIWYG.
So I'd say drop the Galadhrim regiment and get another WE regiment if you can (spare 15 points).
I'd also say drop the Banner Bearers on the foot regiments, not really needed (spare 70 points).
I'd stick with the Hornblower on the Knights, I'd like to have that extra inch of movement (or extra 2" when you go 'At the Double'), but I'm no fan of the Captain. I know you probably have only one box of Knights, but I'd say drop the Captain (and get some more companies of Knights) - (spare 50 points).
Also, I don't think I will ever field Haldir, I'd drop that one also, but that is a matter of taste (spare 75 points).
I've never played with the eagle, but I like ents. The ambush from forests is quite entertaining and it will give you something for your opponent to still worry about. This is something you'd need to find out for yourself.
This spares 210 points total. I'd give the Knights another company atleast. Then I might even get Thranduil (I know it is not fluffly), he is 50points more then Haldir but IMHO way better, still has Epic Shot, even has Epic Strike, and knows the Wilderness spells with mastery of 2. This outweighs the Epic Sacrifice (which I deem useless) and the automatic 'At the Double' pass (which Elf doesn't pass the C test..?). Above that he has F7 and R3, thus a great Duelist as well. Together with the 'Touch by Destiny' of Galadriel you can feed Thranduil might for the 'Nature's Wrath' rolls if needed, ensuring you can do quite allot of damage with it.
But that's just my 2 cents on him, a real bargain for 125 points (but not fluffy though..
).
Perhaps you have some better ideas yourself what to do with the points, but I'd not get too much upgrades (banners and captains) since the Elves are already quite outnumbered, and by taking Galadriel and Celeborn in the same army you already eat quite allot of points.
Hope you can do something with my 'critiques' :p
