Hey Erek. I had a simple idea. Since the foreground is already crowded it would be best to push the pillars into the background.
It's tempting to throw highlights around, but they also betray any sense of depth, since logically anything with highlights that strong is close by. I experimented with removing the highlights on the ceiling for this same reason, but I think keeping them will help reinforce the pillar depth. Also try placing a cast shadow from the sconce, right in the middle there it would obscure its own light on the floor.
Assuming the torches are evenly placed, there wouldn't be highlights on the right side of the statue, I think that light is too strong. I would have more left-facing highlights to reinforce that the torch and statue are foreground.
