I must say you are right above the fish choice thing , last week, all of my angel fish were beaten up by the Oscar and the gars , they were beaten up pretty badly they all died soon after ! It was a mistake ! I decided to make this an aggressive community tank so I got myslef a jaguar cichlid last week .Well, it looks nice, but your fish choice i would change quickly.
Dont worry man I already picked up a bigger tank for the gars . I'll set it up this weekend and cycle for 2 weeks .If your fish are still small and you have no intentions of upgrading in the future... Then i would agree with the above...
As for the aquascape looks pretty good imo

3/5.. needs more plants.. fauna is incompatible with the tank, unless u have plans of making a planted grow up tan.
its a 400 liter effective , 110 GWhat size is the tank? If its going to be empty you could do a group of dwarf / pea puffers...
