To be honest, Doug, I liked your first submission better. The longer thinner neck gave the pose more breathing room and the highlight on the skin allows the head to pop better where now it gets just a little lost in the background. You lava lamp lighting treatment is still my favorite in this thread. The extra colours for the gradients were well spent.
Wyverii's is one of my favorites due to thought she put into the construction. The lava lamp looks like it has real weight to it as it compresses the body and the curled up tentacles actually look like solid shapes that exist in three dimensions. I also imagine it making a *beep beep* sound as it rolls past.
I also really like Gun6's, for attention put to the silhouette. It is probably my favorite pose in the thread being both active and well balanced. The one thing is that the non-shiny lava goop is a bit hard to see. Could you do the same thing with the contrast as you did with the shiny?
I doubt there is any room for me to make an entry, but if I have time I'd like to submit something before the end of the week too...
