It's neutral insofar as that it isn't performing an action, it's just on tilt, so I was hoping that's okay. I was more worried about obscuring due to the angle of the vine, so I could see that.
Any advice on the sprite itself? :)
For starters, the proportions seem quite off; I'd suggest looking at the original art design for CAP2 and its supporting artwork for starters. Its vine connects in the back and the eyeballs blend with the dress. The arms look incredibly thin and it is tough to tell that they have teeth on the ends. The teeth on both the dress and the hood look a little too rounded right now, so sharpening those up would be a good idea.
Also, if you really intend to keep this "diving down" pose, then at least do something about the head. Check this out:
I simply flipped your image 180 degrees. The head looks upside down and awkward. I know you are trying to go for a diving pose with a looking up sort of feel, but the head would realistically be tilted downwards a bit more. Also, the opening in her "dress" would be facing downwards, wouldn't it? In your sprite, it looks like the scoop is on her back.
I personally would rather see a sprite from you standing upright! You seem like a good spriter naturally; so in the end, this is just my personal opinion. Do what you want! I hope this advice helped.
Also, as a note to all spriters, Wyverii is doing something awesome by having all of the "dissected" aspects of her sprites ready to go. As someone who dabbles in animation, I find myself much more pleased with submissions that have the parts of their CAP2 sprite accessible. From what I know of spriting, this isn't something terribly difficult to do, yet it can go a long way in helping an animator. Just food for thought! Loving many of the submissions so far; it will be a close battle!
