Nice one, i bet you enjoyed the clearing up on this one. It maybe just my dodgy eyes but the light on the top left of the pretzel seems a little harsh. Still liking it overall though.
I apologise, I am new to this and you are "stuck" with my comments. Pls. realise that this is *my* learning curve more than yours!
This image to me is "perfect" for this challenge. You worked within the theme and the photograph is beautifully composed. Both the background and dark reflective surface help to show off the main subject, which is in focus and for this particularl image important, very "apetizing" (and I don't drink beer as a rule :-)). Although I am not sure what made you choose a yellow nylon string to attach the pretzel, IMO it does not harm or distract from the picture. My only slight negative comment is the "look" of the pretzel. I have no idea where you come from, to me it looks "plastiky", but I am probably just used to ther types :-). One other minor thing which you may want to consider in future "beer shots" is to use a very cold glass that has some condensation. But that is also a personal preference of how I would like my beer :-). For the picture the clear yellow liquid in the glass (without condensation) works well.
I like your lighting, reflection, background, and salt on the ground. I'm not a fan of the pretzel tied to the glass, I would rather see it leaning against the glass with no string.
