My favorite right now is Wyverii's; it looks very much like something Pokemon would make, yet it stays true to the design itself. The size is very good, but it still maintains that "dainty" or "tiny" factor that this Pokemon has. Good job.
Doran, these colors (especially the shiny ones) are really trippy, which I think is appropriate for a lava-lamp Pokemon. The pose, too, is excellent. One suggestion I have is to make the head stand out a little more against the shell in the background, perhaps by increasing the outline around the head/neck.
Doug, this are amazing, and so is the shiny coloring, but the position of its lips look a little odd. Right now, to me, it looks like it's kissing the base of its neck. Perhaps tilting its mouth up a little more so that the "head" is looking more up might prevent the awkwardness of this pose.
the cones seem somewhat . . . smooshed, making them awkwardly short and wide.Any thoughts?
