We're clearly not seeing eye to eye here. Those texture link you gave...they look hand drawn....they don't look real. I just don't like the way any hand-drawn textures look. They don't have enough lighting geometry and I'm frankly not impressed with how normals and bump maps look compared to real shadows. My textures are from photographs....they look real. Yes, some are blurry, but not all.
Does this look blurry to you?
In terms of interestingness, that's definitely subjective. Most of what I'm showing here are generic materials that are tiled x and y, which is going to require removing a lot of the "interesting bits."
I'd like to understand the feedback that you're giving me, but it comes across more as insulting than constructive.
