Also, you said it was hand mapped I am pretty surprised you could get it hand mapped without losing a huge amount of quailty thats some hard stuff to do, yet you made it look awsome.

Another thing you could do if you still have all the layers and all is make
shadows stand out a bit more around the top plates, and possibly either gradients with them if you haven't already or to make the gradients stand out a bit more if you have.

Hope to see more of this texture.
