1) Try #3 but make the following changes....make the top of the A in PA the same height as the P. Make the + in the A thinner (not smaller, just thinner), and straighten the underline coming out from the A...so no zig zagging, just something that comes straight out.
2) For #3, #2, and #21 please try other colors...some ideas are some softer/lighter blues, as well as try some purple in there as well.
3) On #2 try also making the rectangle around PA just a rectangle...so not quote part sticking out
4) on #1 make the line above Savvy under it, as an underline
Again, for all these options please try different colors...lighter blues, try some purple, etc
