very nice design, i like it a lot. Not sure if you have made other labels and/ or what they look like but i think if you aren't stuck on all b&w you should try adding a splash of color, either in the text or rotor. i think it would really make it pop. just my two cents and something maybe to try. very nice.
light tonig would be perfect, and use as few colors as possible. Just a little something on the main picture and a little around the border to kinda "focus" the label will be perfect.
