I'm not really experienced with iso, so...

What I changed:
The vertical highlight bothered me, because it was splitting something that's actually a single object : a whole brick.
I re-arranged brick limits so that when you look at the middle, you see actual staggered bricks that are 2x longer than their width.
Finally, In the darker side, everything should be darker, including those brick edges. It may not be a problem when doing huge pieces, but here the "concentration" of lines is rather high, so it's rather distracting.
Hope this helps
