aquascape advice

[jxj]

I'm setting up my first reef tank and i'm looking for some opinions on my aquascape. Once I finalize the design, i'm breaking up one of my leftover rocks into rubble and i'll use that to fill in some of the gaps between pieces. I'd also like to get your opinions on gluing the rocks together (and what glue would you recomend) vs just stacking the rocks.

It looks a little like a big letter “M.” But it you use some white E-Marco Cement, you can do some interesting things. Maybe a bit less symmetrical look. Best wishes!
