The problem with "Emergence" is that all the conflict is internal, and that's never as interesting as when it's external, or an internal conflict is commented upon by an external conflict, or whatever. The question is "will he get over himself and get together with her", and the answer is obviously "yes" from the first moment. All the fun has to come from the journey from the start to the end, and dunno if there's enough of that fun there. If you're a B/G shipper, quite possibly. I did enjoy writing it, and I think it has some nice moments and is sweet. But there's not enough at stake. Nobody suffers.
"Emergence" is put to bed. Lessons learned; time to move on.
The problem with the Core Four fic is structural. I wrote myself into a corner and ended up with all the sex from the viewpoint of only two characters, leaving two of our heroes out in the cold. And alas, one of those viewpoints is Willow, and my Willow voice is shaky. I definitely had to end with the Giles-viewpoint segment, because everything builds toward that. (Note that the structure is out of balance anyway!) But I ought to have found a way to write the sex from everybody's viewpoint. And the sex incidents need to build emotionally to the final Giles sequence. Also need to build in intimacy. Maybe a mirror thing: G, X, B, W, smut begins, W, B, X, G. I might revise this story just to see how much better it would be structured that way. Also, it would be fun to write smut from Xander's pov, because I think that boy has a nice dirty mouth.
My first try at writing slash, and I think it came out okay. I do confess to wimping out on the f/f stuff and not being direct and sensory enough. If I try the structure above, that section would be in Buffy's pov, and I think Buffy wouldn't let me get away with being meta. Buffy just isn't meta, the way Giles and Willow can be. And yet, the Giles segment is actually the most tactile of all the sex writing. Possibly because I'm feeling comfortable writing the Giles-voice. Hmm.
So I think that one will get another draft in a while.
