Advice on 25L nano

[Pilaarbijter]

Last weekend I went to the shop to buy myself some hairgrass for my new 25L (7gal) nano.

I purchased the grass with the intention to fully plant it but as it turns out I only was able to do a portion of the tank.
However, I get the feeling that the scape 'has something' but somehow lacks something aswell and I was hoping that you guys might turn me in to the right direction.

Basically, I inserted the grass in the background but topped it off only a few mm. The grass that stands before the tall ones, is the same type just cut off some centimeters more.

Looking forward to your insights.

Sorry for the crappy photograph, was taken with my smartphone.
