What sort of fish are you planning or likely to impulse add?
If you're keen on cichids, I'd choose the more swept out placement of wood/rocks, similar if you end up with wild caught ... not many fish prefer the open expanse, you'll tend to see more relaxed/interesting behaviors when fish can venture into the open areas but "disappearance cover" is only a dart away.
I like wood that crawls over rocks rather than rocks surround wood sort of layout, also "natural" lines that fall between rocks whether the rocks have been scattered or still layered (more) atop each other.
Also remember that when you add water - AND LIGHTING - perception changes ...
I think you have Aquasoil substrate though so less forgiving to fill/empty/refill tank without clouding (though if you're patient & use the plastic "cover" with trickle flow, "cloud" should be minimal).
What sort of plant style are you planning, more "jungle" or more "iwagumi"?
If you're more likely to observe tank from one side (not thinking of front here), then consider if you want a slope from left to right (as well as front to back), rather than the "valley" effect - the difference in perception is quite significant when you have that l.o.n.g slope.
Are you going to leave more wood visible or likely to disguise with mosses? bare wood, like bare rocks, will direct the eye more strongly than moss cloaked.
If I've not said so before, it's a stunning tank & cabinet!
