I don't anything would be under control with Zone-Tan around...
Zone-Tan is one of my favorite characters that the Internet has brought us; I especially like her naughtiness, design and voice. Her voice actress, Caxx, has really made a great work as Zone-Tan. And I'd bet ZONE-SAMA and Caxx would be proud of this illustration :)
My favorite thing about this piece of art is the use of colors: everything looks amazing. The lightning is also marvelous, and the different tones and shades of purple are lovely to watch. I also like the use of dark red for the wine, and how you managed to make it look as if it was really moving inside that glass.
Zone-Tan herself looks amazing: this is one of the few newer artworks featuring her that make use of her demonic-yellow eyes. I really like how you despicted here; though normally those eyes are used for unnerving actions and effects, I love how you conveyed both a playful and dangerous nature with Zone-Tan here. I also love her hair; it is one of the most detailed I have seen on a illustration featuring Zone-Tan. And her facial expression is just the best; I really like the light blush you gave her.
Last but not least, I like the dialogue: though it is simple, I like the suspenseful nature around it, as if Zone-Tan is about to make good use of her companion... I wonder if she's refering to us, the viewer?
I love your interpretation of Zone-Tan Precipitation, I think you made her character justice. And honestly, now I want to see more of Zone-Tan coming from you! (And yes, you should draw your own american comic, I think it would come out delightful, judging by your work here on Newgrounds!)
