I just read through a couple pages of this build to get myself caught back up, and the truck looks amazing. You are a true craftsman.

As far as your question regarding the appearance of the walkway, I think it looks fantastic, but what may be throwing it off to you is the open spaces in the walking surface. In the pictures it looks like the walking surface is expanded metal or diamond plate where you have solid metal with slots. Those slots in scale look a little big, probably a couple scale inches wide. If you attached some scale expanded metal or diamond plate on top I bet the scale appearance would change.

Again, I think it looks great and very scale, just trying to take a stab at what was bothering you when looking at it in person.
