Sounds like a good setup. What I'm contemplating is that I poured a 16 x 20 slab directly on the ground without excavating a level spot to pour it. We have a lot of rebar and the steel mesh to help hold it in place, but I want to eliminate as much water as possible from running underneath the slab where it could freeze and maybe do some damage, so perimeter drains appear to be a must. Using landscape fabric would likely allow any slightly sub-surface water to still penetrate and enter the drainage pipe, I'm guessing, while surface water would easily enter the pipe as well after hitting the rock barrier and dropping down to the pipe. Again, I really like the layout of how you did yours and think the river rock is a great look. Thanks for the more detailed explanation.
