Faceplate and backplate designs

[Shrapnel]

I'm attaching a PDF of what I'm looking at for a layout on my build here and want to double check how it looks to others. This PDF contains both front and back plates on separate pages, and I'm not 100% sure on sizes. (Chassis size is 27 x 2.5 x 7")

Panel sizes are 27 x 2.5"
Large switch holes are 1/2"
small switch holes are 1/4"
rotary impedance switch, pot, jack, and the chromed LED holders from Radio Shack are set up with 3/8" holes.

Panel colors are different than pictured. (I have the original Illustrator CS4 files if someone would rather look at them instead)

Plz let me know of any errors you see. TIA.
