I really like Wraith. Very Cheshire cat, malicious grin. Reminds me a bit of the UC Darigan Aisha. Evil purple kitties.
Pastel is awfully Zombie-like. There are a lot of pretty pastel colors and combos out there, it seems too early in this color's life to be resorting to these shades. I hope they don't try to make every pastel unique that we end up with more of these grungy colors.
Wraith: This has some really intricate swirls and a pretty fierce looking expression. Al of the tiny swirls branching off are a very nice touch, particularly on the tail. No problems here.
Pastel: Personally I think this looks fine, but I can see why people think it looks corpse-like. Perhaps inverting the colors would have helped? Also, I have no idea what's going on with that mouth there.
I personally dislike the outline of Pastel. It looks very rough around the edges. Not appealing. =/
Wraith is gorgeous as usual though! Makes up for the post-Darigan Aisha monstrosity.
