bit of a perspective issue here...

i corrected the pillars on the right
its good to see ur experimenting with brick texture.
i know i keep going on about it i just dont think those bricks should have such curved edges due to the overall size and shape of the highlight and shadow bit.
i also don't think they need to be SO defined from each other.
sometimes less is more as you've discovered with ur lovely red brick texture.
i think u should start looking around at lots of games, paintings, tv shows etc that have bricks in them and keep at it.
and while ur at it, consider some more interesting structures, arches, columns etc. to break up the large sections of brick.
