Sanded Tank Ok?

Does this look good for green corys and RCS? I'm getting some java moss, but besides that there going to be no real plants in there. (I kill plants easy.) Is it too open? Should I add an air stone?

Very attractive. Nice and clean looking. I would add a few more plants, just to give the cats a shady spot. Mine like to congregate on the edge of my heavily planted side of the tank, just under the leaves of my anubia and ludwigia. The shrimp will appreciate it too, as it gives them more surface area to clean off. Looks nice.

Lovely looking tank you've got!
If you want my personal opinion i would have all the plants to towards that LHS besides the smaller one you have at the back there. and even possibly add some more in there (possibly some colour?)
I would also bury the bottoms of them, dont know if you was going to do that anyway but thought id mention it!
Great job though!!!

Haha, yeah, everyone that comes to my house says I have the cleanest tank they ever saw.    (That can have a negative side though.)  
 
Thanks for all the input.  I'll add some more plants as you said.
