Body build critique

Here is what I am planning for mmy body construction.
All voids will be insulated and used for wire runs.
Any suggestions or comments. There is one notational error on the drawing. The floor will only be 1.5" thick. 1" foam sandwiched between 1/4" ply. The drawing shows 2" for the void.
The walls are 1" foam with 1/8" skins.
