gosh, gollygosh. In my (admittedly somewhat inebriated) current state best old-school and best conversion are soooooo gorram tempting. I have been able to summon up exactly zero mojo for painting Ynnari eldar, despite Yvraine being a very nice sculpt, but my brain is full to busting with conversion ideas. Also old school is always cool, so there's that...
Yes. Old school and conversion gets my vote. Konrad - get yer convertin' shoes on. Consider this a challenge

*edit* a question to the administratah: does the conversion need to be painted? If so, does the paint job count for much?
