Looks like you've given the scape a lot of thought. And it looks great to me and part of the fun is in the gardening aspect of it all, so just go ahead and have fun.
Just one comment, I'd put the Anubias in shaded areas, even low-energy with low light they are still susceptible to GSA.
Oh, and also start a journal, it'd be great to follow your planted tank journey especially as it's going to be a longterm scape.
It's also a great way to get very specific help and advice when, and if, you need it.
