Love the wings!

I made my own Faeries & Angels race for Oblivion. I had to in order to role play my characters. It was one of my first mods and I wound up merging Ren's Hair, Eshme's Body, and Alexander's Wings, then customizing a lot of details for the races to be right for me. I don't even know if I could port it anywhere successfully.
People have already ported a small-sized race from a Korean MMO (I think) into Skyrim (Tera? I can't remember now, but it's on Nexus, I think).
I'd suggest using 0.5 scale, though. That's plenty small enough, trust me. It's the scale I used in Oblivion, and it's very tiny. Not as tiny as glow bugs, but still very tiny (as in my characters in Oblivion can stand underneath the leaves of a Nirnroot, that's how tiny they are at 0.5 scale

).
Skyrim's mechanics are a bit different, though. In Oblivion, height changed speed, and weight changed some other stuff, I think. Scale isn't only height, I guess that's the main thing to keep in mind.
