Personally I have to agree with PilotHigh. There are so many textures for sale these days that only the best of the best will actually sell... The ultra-photorealistic textures are THE thing now, check out StefyZZ's Noa and Asia and you'll get the point. Your texture seems to be coming all right, but it's not something I would pay for - sorry if the truth hurts. But, don't give up, keep on doing your thing. I find all this really rewarding even though I've never earned one single dollar with this.
