Your use of diffuse lighting is really nice, it helps to bring out the various textures and tones of the cigars and humidor. The mainly centered, straight-on composition is a little uninteresting, but a well-shot entry.
Personal choice, I would have gone for a slightly darker tone and would have caught all of the gauge. It also bugging me just a bit that the line of the hinge isn't straight in the frame, but that's probably being a bit obsessive.
It's nice to see smoking depicted with some class. The composition seems a little off, I think it's the top half. I know you wanted to include the humidity meter, but if you crop the top down, the composition is much more interesting.
Mmmmm smells good. And I don't even smoke! I would suggest warming up this picture a bit with some white balance adjustment, and maybe saturating it a bit more too.
Good focus and color. Would like a composition that takes more advantage of cutting of the elements in the photo. Right now the croppingof the gauges and the cigars is more distracting. Good craftsmanship of the shot.
