Neat tank! It has a lot of potential! Maybe do some equipment hiding and add some driftwood and more plants and voila! Neato. I love cube tanks they are so neat to aquascape because you have so much depth. 
What size is your substrate? If its too big then the cories will loose thier barbels in the cracks between the gravel (as I have had happen to mine).
