HI everyone. I'm thinking about making a miniature of Finrod, but really don't know, what figure can be used as base. I want something like one of this arts, may be with bow instead of swordoing.
I will be grateful for any ideas.

I would use either a Numenorean or a Dol Amroth miniature. Then add a sword or bow arm from another kit.

Do you want to create an armoured or unarmoured version of him? And are you looking to base it on a GW model, or are other manufacturers also fine?

I find Thunderbolt miniatures to be great representatives for 1st age elves. Check them out if you haven't already.

Gw's LoTR minis in my opinion doesn't fit correctly. They associate with films too much. So this must be other manufacturers I think. Doesn't matter armored or not.
I'll check thunderbolt a bit later. Serving their site by phone is painful.
