An Early Christmas Pic

I was bored in class so I decided to sketch out a Christmas picture. Why Christmas? I don't know, I guess I was just in the spirit. The characters are, Niraka(boy with brown hair), Tsukira(boy with purple hair), Noa(boy with pink hair), Hime(girl with pink hair who's in tears), and Yui(the other girl with white/blue hair who apparently just looks lost). Niraka is actually a neko(I think that's the right term for it. Correct me if I'm wrong). He's part cat and his true features won't show unless he experiences strong emotions such as love, excitement, anger...you know what I mean.
