Beautiful concept and title! I didn't know who Dionysus was, and looked him up.
A little too high-key though - would've been good to see a bit more definition of the wine glass I think.
Artistically very unique. Certainly not run of the mill. Perhaps Jelly from a mould pressed into the glass or a mould of some sort with grape jam/jelly behind it? I feel too much in the highlight dept which blew out detail of the glass rim and base below the stem.
