#31 is very slick, I love how you used the diamond shape. I'd like to have more implied depth and more substantial lettering though. #32 runs into the same problem I've had with my current logo in that the P looks like a "q"
that looks better with #149 in a square I think. I don't like the uneven beveled edges on the right and left sides. I'd rather have on even beveled edge around the entire shape.
