I went back and made some more maps for Alternity, this time trying out a different style. I'm planning on using these as player handouts.

I second this. I used Cosmographer deckplans for vault-like maps to recreate Gamma World maps.

You could perhaps also use SS3 Modern Blueprints to make maps like this:

If I could make a suggestion, I'd love to see a sci-fi/deckplan style for Perspectives 3.

Lol, typical void catto behavior. ;)

Fixed some minor mistakes and spelling errors.

Finished a few more maps, this time from the 3rd edition Lords of Darkness source book.
