I would consider that more medium/light rather than dense. My view is that when densely planted you pretty much see a wall of plants and can not view the other side.
In saying that, it looks great and I'm sure once grown in it will look amazing. I would suggest looking into something that grows tall - like vals or crypt sprialis - to help hide the wall and also give a bit of surface cover - and balance out the aquarium vertically since its rather bottom heavy visually.
Consider getting some nice driftwood accent pieces to really tie the tank in as well!
And allowing your current plants to grow in is also a great idea!
