Spark's Sprites

[SparkMouse]

Couple things.

First:

I changed the outlines back to black for both Yuuta and Rikka. Haven't addressed the clothing shading yet.
If by off-balance you mean his stance, he's leaning back. When I was still working on the outline and pose, the feedback I got was to have him leaning back somewhat (he was standing straight up at first), so that's what I did. If you mean off-balance in another sense, then it would be nice if you could elaborate.
And obviously, there's a third character there; Dekomori. Here's the frame I used for the pose reference, the colors for the outfit were taken mostly from Rikka's (the outfits are identical except for the socks, shoes and bows).

Also this.

Concept/base preview thing for a game idea a friend of mine and I came up with after reading The Oatmeal's strip on mantis shrimp.
