The Frigate Bird in the scheme of my animation is going to themed around the idea of a singer.
The frigate has a couple attributes that I really like, and I can associate with either music, singing or some sort of woodwind instrument or brass instruments.
The red air sac could be in the shape of a heart, so that is something to work off, maybe put it in the shape of a heart. The beak could be changed in order to resemble more of an instrument rather than just a beak.
So in order to get an idea for what shapes and ideas I'm going to take forward for my final design I've looked at balloon reference in order to get a better idea for how his air sac is going to work. I've also taken some reference from flutes and saxophones, just because the whole animal seems like more of an instrument rather than an animal.
I've had to change up how I usually do thumbnails, but I've come up with a good idea for how I'm going to go about developing these ideas even more. So based on feedback I can change these designs pretty fast.
I've got a couple favorites out of this, the main ones being 4, 7, 8, 9, 11.
Any feedback is appreciated, so if there is anything you like or dislike I can use it to take influence into a final design.
