Natural Looking Tank Set Up

[Noahh]

Hi all,
 
I've just moved from a 50 litre tank to a 200 litre which is currently cycling.
 
I'm hoping to create a well planted community tank filled with small schools of small fish.
 
Plants so far:
Egeria Densa
Green Cabomba
Bacopa Monnieri
Dwarf Sagittara

 
Fish so far:
1 x Female Bristlenose Catfish
3 x Ottos
3 x Five Banded Barbs (will get more once tank is cycled)
1 x Neon Tetra (last surviving, about 5 years old)

My tank is a second hand Fluval Roma 200 and I've got a new Fluval 206 Filter.
 

 
I'm really wanting to create a natural scene with what appear to be natural fish.
 
Can anyone who's done this before give me any pointers? Like things to watch out for when trying to make my tank look 'wild' or 'natural'?
 
Thanks,
Noahh
