There are lots of character packs for Aiko and they vary a lot in style, because A3 can go from very stylised to "realistic".   You could have a look at the vendor pages of the likes of Rhiannon, Syltermermaid, Peti1958, TFDesigns, rebelmommy, Nouschka - there is plenty of choice.   You may want to pop over to www.render-spice.com, too, because Nemain Ravenwood has quite a few items for Aiko and she doesn't sell here any longer.   Another place to look  is www.planetvixens.com.
