If you're happy with it, run it. You're the one who has to look at it all day and enjoy it. Who cares what someone on the forum says. Sure there may be some helpful suggestions (such as making sure you have caves/hiding spots/rocks away from the glass so you can clean easily and the such), but if you're happy with the way it looks go for it.
It'll look quite different once you get some corals and other colours in there anyhow !
Ps. Welcome!
