What should I change now ?

Uhhh....nothing! :) Gee whiz, it looks heavenly!!! :hearts: The contrast between the various angels, swordtails, and the black mollies is just divine. It looks like a perfect little world. Thanks for sharing. ;)
 
I love everything. The only thing I'd change would be the background, but then that'd kill the color of the Black Mollies. Maybe dark blue? I wish I can have a tank like that.
 
Try a bare bottom look maybe...?

Seriously....a large artistically shaped piece of driftwood to set off the vast upper emptiness on the right.
 
Thanks for the comments.
The background won't change any time soon, believe me , I've thought about that.
I also am considering more driftwood with the java fern to fill in the right side . The amazon sword and broadleaf sag should fill in nicely on the right side also.

Never a bare bottom for this tank my friend :)
 
Looks like a dream tank!
 
Looks great! Maybe add some kind of canopy/surface plants, or some large pieces of drift/bogwood? That would be the only thing I could think of. Looks really good as is to be honest.
 
Absolutely gorgeous. I like the idea of a nice piece of driftwood on the right, but honestly... it's just beautiful. I wish I had a tank like that.... sigh....
