I think you'll get lower marks from people that only know the Deathwiong as being Bone White. In the fluff it clearly states that they were originally Black ( same as the Ravenwing are now ). I like the painting and the "pre-40k" colour scheme. Well done.
cool banner, you REALY need to thin your paints...once you have that you can get smooth blends...judging by this mini once youve sorted that out you'l be pretty good at this.
