For #3 and 4: I like the way you've used color in these logos. What I realized after I saw them (and then updated my brief) is that because of the color and the sort of stern nature of the raven's eye, they remind me of the logo of our regional football team, the Seahawks. I'd prefer there not be that association. Here's a link to that logo:

Thanks!
