Great sense of depth and three-dimensionality. This may sound silly, but I really like how you made the griffin's ear look plausibly realistic with a bit of a fleshy earflap on the inner part and feathers ringing the edge. It's hard to put mammalian ears on a bird head and make them look right, but you did it well!
oi, woman, you are giving me serious traditional art urges with these pieces. It's gorgeous - I love seeing the process images too. You're really coming on with your colour control too, there's a lovely level of saturation without it being too gaudy.
