This looks awesome I love bold choices. Keep the planting simple for contrast. With a big statement piece like those rocks, you don't want to muddle it with too many different plants- iit will only make the space feel cluttered. You can totally do that tank with those rocks just my $.02.
superb set up.
if you went with a black background in the future it would make the bulkheads vanish.
i love the large rocks, simple but effective.

The sloping really makes it work! Funny, though: my wife said the rocks look like Jabba the Hut. You can see his face right at the top of the highest one, haha...This is why I love her - she caught it before I did!
Anyway, that looks excellent. See the shaded areas at the base of the rocks? You might have trouble getting certain plants to grow there (I've had some experience there). Maybe something like lilaeopsis brasiliensis or or l. Mauritania in those areas - grasslike but they don't need high light and fare better when shaded. That will give you a similar feel without the trouble, though they do grow slowly. I saw Amano do this in one of the video workshops on YouTube for the same reasons.
