I love it! For your plants (since they're swords) you'll want at least 2 watts of light per gallon. It should be bulbs around 6700K rating. Trust me and do not skimp on lighting, because nothing will ever grow with the wrong lights...trust me I've made that mistake. You'll also probably want some root tabs because your sand doesn't have any nutrients in it at all. I use the API root tabs in my 15 gallon that has play sand and it is growing great. You may also want to look into some Flourish excel (easier and cheaper than CO2 injection on a smaller tank). I use it and I think it works quite well in low light situations. I am by no means as expert though, but I have finally gotten my plants to grow well so I figured I'd share.
The background looks really good :)
