I'd say that's much better, but I think a few more caves would be better. I've noticed a lot of inverts hide in caves all day and venture out more at night, so a few more caves(even smaller ones) would probably make them feel a little safer.
Also, I think we have the same sand, I used it in a shellie tank(cichlids). Was it as big a pain in the ass to clean for you as it was for me?? All the other sands I've used have been pretty easy, this one, not some much.
