That's a good effort, and I really do appreciate it... but I was thinking something closer to a narrow, contour-following, rock-clinging wood walkway, or even a bare stone ledge. And I mean narrow, like scarcely room for two cats to pass each other (ergo, catwalk). Maybe something organic to the type of terrain or typical of scarce timber, truly precarious and rickety, meant in appearance to complement the fort's strategic nature were such a place real. (But all that nuance might require 3DS Max.)
What we have here is a kind of elevated super-highway...
Yeah that was just a beta lo,l im going to make the final version soon, will be like you said, it will be a wooden walk way along the side, ill use some nice matching textures to go with the fort to blend in and it wont look like a massive stone highway.
