With a bottle of red wine

One of the drawing that I've spend more time one than I usually do. I kind of decided to try to spend some time on it, so...

Inspired by the song
Lady Gaga - So happy I could die

Where the lyrics says:
Happy in the club with a bottle of red wine
Stars in our eyes ' cause we're having a good time
Eh-eh, eh-eh, so happy I could die

Also tried to expreiment with shadows and lightning, but I think I kind of lost control over it ><.
Whatchu guys think?
(I don't mind critique on it ^-^)
