Hi there and welcome!
Right now it's a little hard to comment on the model. Can we got some more views? what exactly is your intention for this? Is it a wall, smaller stones that you'd see laying around some ruins?
At the moment my initial feedback is that you have a lot of cracks going through the model. Generally you'd expect that when there are so many cracks going through stone, it would have some chunks missing out of it.

I would also try to play with color variation, like more brown-ish tones and lower the spec/glossiness. Hope that helps!
