Talk about niche marketing.
Not to mention ego.
How do I put this...do you want to make money in this business or do you want every one to be talking about your gory label that you believe to be artistic (on the slim chance it gets label approval)?
Don't confuse the two. They are not the same thing. Both might be considered 'success' but which mindset is going to pay your bills and allow you to continue?
While I agree that my perception of 'art' will differ than anybody else's, it should not be, even potentially, a barrier to my purchasing your product.
If you are comfortable with immediately alienating me as a potential consumer based on your label artwork (which you have basically stated), you might consider another business.
By the way, the difference between Flying Dog/Oksar Blues and your situation are twofold, wit and subtlety.
Best of luck,
