Agered with Lindion45.

I think the gap would read better if you had a transition tile from the green wall to the red wall, perhaps a rounded one, with the light going into the gap a bit.

Looks cool!

Readability for the tiles in the gap is a bit low though. It's confusing because you use the dark red for wall tiles, but then the wall ends and the tiles are still red!

Also the brick dithering looks a bit wierd with such high contrast between the bricks and the gaps. 

Finally, the pole looks very detailless in comparison to the rest of the piece!
