This is a great military macaw. I like Parrots and i like the new lego colours. Too bad that they are not so common, yet. I have some other parrots, but I wanted to create one which does´n need a stand to stand.
I'm not much a fan of the way you have it connected to the base, but the way you made the colors fade to the next on those tail feathers is beautiful. It there is a betterway, I would try to find one for it to stand than to have the feathers just kind of squish at teh bottom instead of make a nice smooth stop.
I think that this parrot is just as nice as your other animals, but I think that a stand had been better, it looks a little odd that it stands on its tail feathers holding a piece of branch with his claws.
