Hello,
Interesting themed army, but I guess you know it won't really be competitive (I'm not a great player, so it's only theory ^^) :
- lack of strenght (only Forlong, Imrahil and the knights with lance have real killing power, no?)
- lack of magic (to counter big heroes or monsters?)
+ reasonably good numbers
+ mobility (horses)
+ defense (except for the bowmen)
BTW, blackroot vales archers seems to be weak (F3, S3, D4, C2...). I understand why you've taken them, but I'd change them if I could, even though I really like the Duinhir's miniature
Don't you want to include Army of the Dead because they came later in the fight? With good defense and terror, they might be really good against Mordor (front rank, supported by men?).
At a higher points game, it would be great to add Gandalf the White, for theme
Such an epic character, IMHO (point sink, however ^^)
Sorry for the poor English
