That ain't pruning! That's a 'deserting'!
Did you remove a bunch of plant species? Have you ever had a ground cover?
What you have there Joe are growing beautiful discus with the foundation for a lush planted environment. But I agree with your assessment, maybe put a few more somethings in there. I myself prefer the lush look. But discus look good in bare bottom tanks too, so it is hard to go wrong.
I think the high fin blue diamond is my favorite too.
