Aquascaping Critique

Looks pretty good.
But I'm Aquascaping challenged, so maybe my opinion isn't that great? lol.
How do you keep your sand so neat? I've tried it and it kept blowing around the whole tank, like a mini duststorm.

Cory cats.......... lol, they keep it looking clean, but blow it all over the tank as well. I am looking to get a heavier sand at some point in the future, I have playsand now but think the grains are too small.

It's amazing what switching a background can do. Looks really nice.
