First off may I ask if this is going to be high tech?
IMO i think you should make the rows of rock closer to take up less room, it will also make to have a bigger foreground area for a carpet (more for high tech) and then if you were planning on stem plants you would have plenty of room there too.

I'm certainly no scaping expert, but I think it looks awesome. My only concern would be getting it to flow with such a small amount of open space. I would start with the larger anubias nana on one side then transition to the anubias nana petit and then to the smaller Buces... but there may be other ways to do it to make it look natural. Like I said I'm a beginner.
That is going to look killer... get some pics up of the apistogramma!! Are you going to keep the sunfish with the Apistogramma?
That rock scape looks awesome. What are you planning to plant? High tech? After a few weeks of C02 I will never go back to low tech. I'm struggling to keep C02 out of my shrimp tank. Is that your main colony in the tank with the Apisto's or do you have a shrimp only tank set up?
