Bird in the Trees

Lots and lots of good techniques used here!
The textures are nice and have this great hand painted feel.
the parrot is easily identifiable and looks very nice and realistic.

I recommend sharper shaping on the beak, it looks a little bent near the middle.
Also the green in the feathers is a bit too similar to the green in the trees. Maybe warmer colors or a different shade to contrast. Otherwise the bird blends into the background and it becomes less noticeable.
Adding heavier lighting and shading can also out this contrast.

You have a great style that looks very similar to painting and I can tell you worked very hard! Excellent job.
