Love your color! You have achieved what many long for with those intense reds!
What's your lighting?
Do you think you still might have a few too many grassy looking plants. What about downoi? How about something with a round leaf, like lobelia cardinalis, anubias. I'm talking mid and foreground here. You have a lot of interest in leaf shape and size in the background but as you come forward it's not there. Just an idea.
