Very nice looking tank.
Love the reds in front.
Usually I'm not a big fan of printed backgrounds, but I think you are making yours work.
Will you be keeping it high on the sides and low in the middle?
If so, will the middle grow to hide the heater?
I think the heater is a little distracting presently.
One thing I'd suggest to think about is creating a focal point.
I think things almost look too busy, with the wild profusion of various healthy plants.
55s are tough to scape well - I think you are well on your way.
A little tweaking here and there will make tremendous difference.
Thanks for sharing.
