Well, first of all, IK_Jane has got to stick out that chest! Lead with the primative goods! Head back a bit. I noticed her hip was swaying, that’s good. But you’re right, she will be in there for a couple seconds at most. That doesn’t leave much time to ‘sachet’.
I don’t think the jaw will be a problem. Even if it looks like his mouth is ajaw, that will still be appropriate. What I’m worried about is the eyes. If I remember, IK_Joe doesn’t have much for eyes, and I think they are very important to any reaction he could have with IK_Jane. Bug eyes, Wide eyes, eyes that are casually gazing to focused laser-beam concentration on Jane… All hard to do with the two small black spheres I remember on IK_Joe.
I’m not saying it’s not do-able, I’m sure a lot of supportive body movement could compensate. I’m just saying that if you havn’t spent too much time on it yet, maybe Mr. Generi could oggle another Mr. Generi in a dress.
Oh, and I know how much moving can suck. Good luck. It’s Hell.
