Map size is roughly 88 x 88 and 37 blocks tall. Again, it's mostly world edited with //copy and //paste done to those mini-houses. Too many mobs spammed across the terrain, hardly any stone to speak of. It's still a bit too small of a build, since there are five timers, each wave would take (assuming these timers are spaced out evenly, like with the other sub) roughly seven minutes twenty four seconds per wave. Even then, this map is still very small, so everything would be flooded before anyone would have a chance to really explore much.
I can't entirely say this would handle well with RoF, to be quite honest. Again as I said before on the other submission, you're getting better, but you're not quite there yet.
