I see: Meiling - Upper right (you can see her hat with the star on it.) Remilia - Lower right (hat, wings, bow) Aya - Below Remilia (hat, tie, shirt.) Yuyuko - Center bottom (hat) Youmu - Obvious Cirno - Obvious
That might be Yukari in the middle, judging by her hat, or it might be one of the various fairies, or possibly a fairy maid.
Agreed on Mystia's shoes. Not sure who's shoes those are below Youmu, though.
Meiling - Yeah. Remilia - Yep. Aya - That looks more like Sakuya to me, judging on hair color, western style shoes, the garter strap, and what looks like a maid headdress. Yuyuko - Yes. Youmu - Duh. Cirno - Again, duh. Yukari - I can see it judging by the dress's seemingly purple appearance and cleavage, coupled with the long blond hair. Mystia - Look more like Patchy shoes to me. Mystia's have little winglets on the back and no ribbons. Dual colored ribbons are a Patchouli thing and the boots look naturally lavender judging by the shaded portions.
