Id stick a white or black background on the back of the tank.
also I'd make a clump of elodea and stick it in the front left corner to give something with a bit of height, good colour and not being too visually obstructive...plus fish love to nibble on it.
I just lay a few strands out straight on the ground, tie the bottom end together with some nylon thread and stick it in the substrate.it looks so much better than trying to stick individual pieces in.
