I find it profoundly lacking in ramps AND ledges, FG. My expectations in this category have not been met!
The only real comment I have is that, given who lives in there, some branches up into the negative space at the front my be a good addition. The plants look great. I used to have a bunch of that Peperomia next to the brom at the top but I lost it to a massive oak-leaved ficus incursion that happened seemingly overnight...
