This is Xanost's classic Succubus freebie, as converted for PC by 'underdog'. I changed the base figure from P3F to Posette with CR2Editor, added appropriate costume then played with the textures...

The conversion looks good!
What a coincidence, Today i created a dark fairy too; but I used Anan {New Judy}, some clothing fitted to her, & wings from a dragon. The effect is very similar to what you've created Nik.
 

I'll post mine to the gallery (since it features a "Posette").

She looks very good ! Even if the atmosphere is a little creepy for Tormie ...
