Thanks for all the positive feedback guys!
@Mokugino, I wish I had the time on it to produce actual 3d slate tiles or even a good displacement map for the roof but with the time constraint I was very limited.
@Jenujacob I used displacement on the stone walls, Stone caps and some of the grass. Had I had time I would have liked to made a real displacementmap for my stone texture, but again time limitations only let me make a very crude one. as far as the grass goes I used a combination of my bilboardgrass(forever recieving more tweaking) and a modified version of Hikaru's displacement grass. then in photoshop I used a hue layer to give a slight color variation pattern to it to give it a more realistic look.
@javadevil, Yeah we had 0 budget on this thing so my timeframe was severely limited. I was only able to do 1 pass on each shot and would have liked at least 5, but what do you do?

Anyways thanks again for the great feedback guys!
