From a design perspective theres a few things I'll point out, but art is such a personal thing no one can tell you what's right or wrong.
The letters in front of the oval don't make visual sense since you used a scroll, which makes you expect the letters to be on the scroll. A wavy bar of color or some other graphic might work with the 3 different layers, but the blank paper doesn't make sense.
Also, the image I'm guessing is supposed to be hops? When I first saw it I thought it was something under water. It looks like some kind of green walls in the ocean for some reason (maybe some of the white edges giving me the impression of bubbles).
By the way, I really liked your books and dark glass label; that had a lot of character.
