Cholla wood arrangement-any ideas?

So I set up my 10g tank with all the plants and now I'm deciding where to put the cholla wood. I'm currently just messing around, but what do you think? There are 3 pieces, one over by the filter in the back left(I was thinking of having that corner be a good spot for the ghost shrimp to chill and graze on the sponge filter), and the other two on the right side.

I think that your current arrangement is really good. If you want something different, maybe try to overlap two of the pieces.
