Excellent job. You'll want this photo -- in a few years, the pick and pull foam will start to fall apart (I've done a LOT of pelican cases for AV gear) and you will need to replace it. When you do, you should consider going with a solid sheet of open-cell foam, and cut out the exact shapes you want. It will last longer than the pick and pull, pretty much until age has deteriorated the foam itself. (Don't use a toolbox style foam like Kaisen or Shadowbox. They are great for tools, but don't give enough for guns.)
Putting a contrasting color (like orange or red) 0.5-1" foam underneath is pretty vital, too. Gives you instant visual when something is missing.
I like it, good ideas, especially the contrasting colors.
