I love the buddha head but it's the whole focus of the tank. You can do so much more but adding more substrate, adding a lot of rocks and wood and kind of hiding the buddha head on one side with lots of plants surrounding it. Make it look like an undiscovered ruin in the jungle. It's all about composition. Some people make the mistake of putting something spectacular smack dab in the middle and then adding equal amounts on each side. Wrong! Off center and everything in odd amounts, 3,5,7..... build hills and valleys with the substrate. This is just my way of doing things but it's really all about what you like.
