Good work on skipping the forms; if you make me fill out a form before allowing me to download something I'm going to be mashing the keyboard with my palm.
Emailing people to solicit feedback seems a little bit weird. Just put a note somewhere (where it will be seen) reiterating that this is version one and you would really like any kind of feedback.
If that's not working, figure out some specific aspect you want feedback on and put the question out to a forum. For example I've seen some amazing UI design feedback come from cold-call requests on HN.
