I think it looks quite good, although lacks that certain something to make it stand out. Maybe adding Tyrion will provide it.
The blending on the skin looks very nice and the griffon\'s beak looks good. The borwn feathers, though, look a bit messy. Perhaps its due to the photo, but I think they should be better defined. The same goes for the middle-brown feathers on the wings.
I hope to see the griffon again with its rider added.
BTW, I voted on it and gave it a 7. Better definition on the feathers (or, if that\'s the case, a better pic) and a smashing Tyrion riding it would raise my vote considerably.
Cheers,
