Totally agree with Jakiebabie, you have a good foundation, just need to tweak it here and there to give it more oomph
Perhaps a darker colour mixed in with your substrate so it doesn't look too stark?
Google lake beds and such, have a look at other aquariums on here and you'll get an idea for what you like
