tikal the echidna sonic advance style

[Garamonde]

I know that her arm on our right is probably supposed to be pointing directly to the side, but her hand looks... really weird to me. That index finger looks as if it's broken because it's pointing straight out like that. Maybe you can kinda make it at a slight angle? Or maybe even more shading near the base so that it doesn't look bent out of shape.

I know this doesn't make sense but I'm not good at explaining, so... if you need another example I can try to give one a bit later today.
