Spark's Sprites

@Previous: Is this better?

I agree the shading on the umbrella was wrong; I wasn't sure how to go about it since I haven't shaded/highlighted that kind of object before. I went through two or three other versions of it before moving on to the next character, but this one definitely looks better.
I tried adding a shoulder, although I'm not sure if it looks that good yet. I think I need to round off that general part of the arm.
I also fixed the banding pretty much everywhere, as well as some of the outlines near his left ear; apparently I had missed that bit? You'll also notice a lot of the jaggies are gone.

@Gors: I generally see colored vs black outlines as a stylistic choice. Sometimes it looks a lot better to have black outlines (and makes it simpler to keep a consistent style with a lot of different characters), and others it looks much cleaner to have colored outlines. With the Ancient Minister, R.O.B., and Pichu, the black outlines (or really really dark-colored outlines, in Pichu's case) are to keep a consistent style with all the other characters. For the Ghibli characters... well, the movies don't have colored outlines on the characters. It's always a thin, black outline. However, outlines which are not on the outermost layer (touching the background color) use a darker shade of the appropriate color rather than a black outline. Probably most noticeable on Mononoke, and I haven't quite gotten to do that with Robot yet.
As for the colors, can you give specific examples, as far as which sprites and which colors could be used? I understand what you mean, but it's kind of hard to see what you're saying on this one without some specifics.
Also, I see what you're saying on the animation part. When I return to working on Pichu to finish up his missing animations, I'll see if I can mess around with it and give some of the starting frames more power, and add a few more startup frames.
