Aquascaping Help

[JConner3]

I've been messing around with the scape of my tank and I still cant get the tank to look "good"

The plant I'm currently working with are:
A large amazon sword, some green and bronze wendtii crypts, 2 different kind of anubias and some rotala indica. I also have some ludwigia palustris that I wanted to put in and some water wisteria that I can tank from another tank.

I bought a couple of pieces of driftwood to replace the fake ones that I have but I think they may be too small to look right, and I found a few good sized rocks outside that I want to use.

Im running 36 watts of t5 light
PFS substrate with root tabs
And I dose excel every other day (switching to DIY CO2 over the weekend)
