I'm guessing you tossed alcohol in there and set it aflame? That's a great idea! Hot chocolate flambe'. :)
I expect you wanted the light level lower than not to ensure the flames were easily visible, but unfortunately having that dark background emphasizes that somewhat more highly than I'd prefer. Also, while as usual I know that "shoot your subject off center" is the big trope, I disagree when it comes to single-image-vs-plain-background shots, as significantly uneven use of negative space just makes me want to start editing... but you'd probably get as many people telling you the opposite. The compromise would probably be facing the handle the other direction.
And, in fact, the only way to bear chocolate is with brandy in it in winter. Love the wood, love the glass and the chocolate - the flame is a little lost against the rim of the glass?
Nice idea, but I think it's a bit too dark and I'm not sure about the angle.... perhaps a different background colour would help or a tighter crop.... not tryingto be super critical, just trying to help :) Godd luck, Todd.
