It's the texture

Oh my goodness, that really is terrible. Advice to OP:
You see this shiny lego brick? (Click for full size)
Notice how lego bricks have rigid angles and clear-cut shapes. They are reflective because they have these polished, flat or evenly-curved surfaces. The "glare" or reflective "gloss" quality comes from the edges on it. Notice how the sheen is in very specific and confined to certain areas. This is due to the surface reflecting a limited amount of light vectors. Blockland bricks are supposed to have this same quality if you wish to make them shiny.
Now look at this smooth rock (Click for full size)
Notice how the surface is blended and round. Although it does appear pockmarked, the sheen or glared surface is blurred or blended with the surrounding area due to its reflective surfaces picking up more of the surrounding light sources with varying strength of the light reflecting off of it. Your textures seem to mimic this more.
No one likes my brick texture hobby.
No, as may others iterate:
We would like it if you would try and practice and do a better job in the textures.
And as I articulated clearly.
