Looks good.
One thing i would say is that make sure you leave oplenty of room for those back 2 headers around the footwells. It has taken me hours on my car to fix the headers in position because so little room when the footbox is so close. It was easy when i dry assembled, but once i had gasket selaer and gaskets in place the job turned into a nightmare.
I also made my own footbox covers that cover the steel structures on my chassiss:
