Nice! Have you considered adding flocking (https://en.wikipedia.org/wiki/Boids https://en.wikipedia.org/wiki/Boids) with lots of them flying around? For a "useless stuff" project, I coded this for bats (all the same model) flying around. It's really fun to play with the flocking parameters to make them behave like bees, fish, birds etc. and it's not much more code than a regular particle system.
