I'll look into Wood and Moon elves to add.
A portrait pack integrated with Aric's Mod for subspecies? Well, I've started putting aside pics that fit with the subspecies as I'm working on a portrait pack anyway, so if you're looking for something in particular now, just let me know and I'll get some together. As for integration, with the Randomportraits mod or similar... I was going to say no, but that's an interesting idea. I think I might enjoy tweaking that and getting it to work to my preferences, so let's call that a maybe (assuming I can figure it out, it's not a ton of work, and the author is ok with me releasing a new version of their mod).
