Seems fine. I don't like
Inside A Song and given that you're not reinforcing any tokens, it seems like you'd be better off just packing more skirmish pumps like
Supporting Fire (which is not standard, nor is
Greenleaf; if you include those cards, this needs to be in the Expanded forum),
Point Blank Range or
Kindreds Estranged.
You might want some way of making forests for
Kindreds Estranged and
Standing Tall. Obviously Gandalf and 4x
Traveled Leader is probably the best way, but given you want an Elf deck I would suggest (in expanded) packing a ranger Elf like
Glorfindel, Eldarin Lord or ranger versions of Arwen with
Pathfinder or
Well-Traveled, or
Get On And Get Away (which is R-rated in expanded); or (in standard) with
Uruviel, Woodland Maid.
I would also suggest that
Sword of the Fallen is much better than
Blade of Lindon, but site path control does also support the blades.
I would also consider using
Nocked which is a decent wounding card which will help
Queen of Elves and Men.
And I think I would use
Galadriel, Bearer of Wisdom mainly because your strength pumps will work on her.
