Nice build !!! But do not over-use bricks. It's a nice detail but it can easly create a chaotically and heavy look.
This is the feeling I get when I look at it… said with respect !!!
Constructive criticism:
A) When you use tiles to illustrate bricks it's all about where to place them and getting a balance between them (the composition). A simple trick is to devide your wall with a imaginary diagonal cross and only use tiles in the corners and the center. Like a playing card of 5. Sounds weird...
Now only put tiles/bricks where the spades are. Nothing can go wrong now. What ever Lego parts you already used in or on the wall (windows, doors, ect). The only thing you now have to look out for is the rows of brick you use. Best thing to see this is looking from a distance to your moc.
B) Try also to mix a few tiles of a different shade into a wall of primarily one color (for example: red, dark red).
C) Or use panels/walls. Here the stones are already printed on and in a good opposite & proportion of each other.
For example:
But there is a fine article on Classic Castle over "Avoiding the Big Gray Wall Syndrome".
