Yeah, I'd be getting a little worried, myself! And dammit, at least we won't have to see stupid Nicole Kidman, Carrie Underwood and all that other bullshit in Pittsburgh. -_- Maybe that's just me, I don't know, lol.
That sounds like quite a rut to be in. Maybe try some actual (but relatively minor) bonding moments? I mean, from what I remember of Snowfall, there's a lot of room to fill in for the whole 'post-hero' high of the relationship. Yeah, Sensei was a complete douche, at first, lol, but he did see the light, in the end. So, while she did experience some trauma, regarding him, there needs to be some trust formed between them. Being her, you'd have to think there'd still be a part in the back of her mind that is afraid something terrible might happen to her, again, and that it's possible he could be connected to it, like before? Sensei just needs to convince her that he'll never go back to that terrible past, and that he's going to always be there to protect her from the Touko's of the world, lol. (Or the sleezebags connected, or not connected, to her)
Is that ok, for starters? Like put her in a perfect storm scenario where she can be fearful of his past, or hers.
I feel your pain with posing and comics, as I've also been in a complete rut, myself. Thankfully, I think I've FINALLY come up with a couple things to go off of, and so you and everyone else should be seeing a lot more Sylvia, I think...
Oh, and have you noticed how much less sexual stuff is being produced, lately? I can't say anything, because, I've been almost primarily ecchi from the get-go. I've been itching to really buck that trend, though, but urrrgh, now I care too much about my girls! >_<
You ever feel that way?
