"Remarkable bird, the Norwegian Blue, idn'it, ay? Beautiful plumage!"
Sorry couldn't help myself. You say parrot, I say... well you get the idea.
I do agree that these need a little more bird in them. Either verticle or an interesting landscape. Looking at the first two, I feel like they're just a tad underexposed. The white around the eye might pop a little if you upped the exposure just a hair (As Kmh said, fill flash would have helped a lot). They also do feel a little soft.
Still, interesting shots.
