http://en.wikipedia.org/wiki/CG_artworkCG is a term most commonly known in the West for its use in Japanese webpages to denote digital artwork. In traditional Japanese, it is an abbreviation of the Japanese gairaigo computer graphics (コンピュータグラフィックス?), used to refer to any form of digital artwork, from digitally shaded dōjinshi to legitimate cinematic art (like Toy Story)
In this context, while pixel art technically qualifies as a type of CG, the denizens of Pixelation typically will distinguish between pixel art, in which every pixel is individually placed, and CG (in which you might use tools such as soft brushes, airbrushing, filters, rescaling, etc.)
In this thread, your CG would be the first image you posted here

.. or the larger version of it.
To be quite clear, the problem was not with the head specifically, so much as the entire body. The darkness on the neck gives the visual cue that the head is a fair amount forward from the feet. If his other limbs (wings) were resting on the ground, this would not be an indicator of falling over, but as is (with his wings up and head down), it is.
I believe that there's a basic problem in the planning of this image, ie. making sure everything matches up and makes sense both with regard to perspective and body weight distribution/posture. If it were me, I'd be going back and trying to come up with a fixed version of the basic design, and building a new rendering off that.
On the subject of the wings, the pattern you have put on them doesn't match the angle of the wings. Each individual segment of wing is at a different angle to the camera, and when you put a pattern on them all without any variation, it flattens out those angles.
You've definitely improved the detail level, good job there.
