People that seek genuine-ness in art can spot a fake. It sounds trite but you do have to be true to your interests, feelings and inner senses. That is the only satisfaction if you desire to be a "hard core" artist. Now I'm not saying there's anything wrong with making a buck off your work but you need to ask yourself, "is this enough for me?" If the answer is "no," then you probably won't be very happy pursuing that path in the long run. Now if you can make a living doing what you love, that is the ideal, isn't it? Hell, as an artist, you're lucky if anyone even considers your art, let alone PAYS for it.
So I guess what I'm saying is that you shouldn't be afraid to do what you love. Wear your influences and your heart on your sleeve. If people laugh, hey, at least they noticed.
And remember, irony is for cowards.
