Arsdel,
I like the overall composition, but the curving iron going right into the corner is problematic. It leads the eye right out of the frame. Recropping so it exits on the left, or better still on the bottom would be better.

I'd do a little cropping, too. There's some nice detail in this mocker but a little too much sharpening around the head and tail. Also, there's a lot of noise in the BG. I'd definitely select just the bird to sharpen (also avoids halos) and then if there is still noise in the BG....use a small amount of blur.
