Looks great! Those plants will fill in nicely. My only suggestion is to use a wee bit more sand in your sand cap. I see a few places where the potting soil is too close to the surface for my comfort, and it could give you a hassle during water changes (which, by the way, should be done by placing a plate down on the sand first and pouring water directly onto the plate).
As for foreground plants that do well without high tech, have you considered pellia or subwassertang? It's the loveliest green color, fish and inverts enjoy hiding in it, you can arrange it however you want and it doubles in quantity every month. This doesn't seem like a lot if you start with a small sample, but by the 5th or 6th month it's really impressive. And it also doesn't block out other plants, it just sits wherever you've put it, and doesn't grow upwards much. I think I started with a half a cup around a year ago, and now I have a sizable amount of the stuff. It's still my favorite plant, and it requires very little light or nutrients to thrive.
