C&C for Sprites: Practice, possible game. Need help

[Butler]

I don't quite like her mouth and ther eyebrow. Maybe use the same technique you used on your first character. The water jets don't look quite right either to me, looking more like a bone plate or fin sticking over her near shoulder, making me feel odd as to why there isn't another one on her opposite shoulder. Also the tail looks o be attached to high up in my opinion.

I also just noticed what your style reminds me of. Metal Slug.
