I think it looks much better with the wings upside-up. I also think a larger head would be a little better.
As far as the charities-as your event is sponsored by the Blue Knights, you might check in with them and see if there are some bike charity events that you could send your donation to (Susan G Komen foundation tends to have a fair number of bike rides, and there are usually at least a few veteran's rides in any area, and there are load of others every summer). A lot of that, of course, depends on whether this is really going to be a bike-heavy event, or if it is more that the BK's are putting it on, but it is not expected to be a 'biker' event. If it is going to be a 'biker' event, be sure to have loads and loads of packing material, as even small items like that need some cushioning if they are going to go in someone's saddle bags or tank bags.
One year, at a charity ride, I won a huge dog bed....that I had to try to carry home on my bike. Don't ask me how silly I looked rolling down the road with a giant dog bed (for my little Peke mix) strapped to the back of my bike.
