Less stuff heaped in #19 I would love to create the logo that you really need but I please ask that your criticism is constructive (i.e. what to take out of the heap)!
#19 I apologize for being abrupt, I'll try to do better. The night sky is cool. I didn't like the sapphires, they looked too much like bubbles. My husband is right about the color of the state shape being the same as the circle, it was confusing. Maybe if the state outline was more like a background banner (since it's roughly rectangular) instead of sticking out of the circle? The grain is okay but maybe a little stiff looking. I like the shiny gold circle and the rivets. Not sure how to feel about the bottles. It's a logo, for business cards, letterhead and such. But it could also end up being the neck label on a bottle. So bottles on a bottle might be redundant.
Thanks for the expanded feedback! #20 plays off the iconography of the skull and crossbones (often associated with treasure) but in a completely Montana/brewing way! I chose the cow skull because of it's place on the Montana state quarter.
