Call for Pokemon smilies!

[Underscore]

So I actually attempted this Serperior smiley last year and I only bothered to present it now. Problem is that he is facing the opposite way. I use to sprite a lot back then. I'd love to help but it may take a while for me to get the hang of it again. So what do you think about the Serperior? The hardest part was definitely the tail since it's hard to put detailed parts in a small space.
I notice that, in the smileys already made, there seems to be different styles of spriting done. Some have black outlines and some don't. Some of them are actually pillowshaded. Someone should edit these to make the style uniform for all.

I'll edit this one with black borders later.
