I've collapsed acts 1 and 2 into a single act, so I'm working now on what would've been act 5 (but is now 4). I've been consolidating and removing breaks between scenes significantly and lengthening the new scenes that I write. I'm hoping that it makes the whole story flow better, but there's also the risk that I'm just filling time with useless...stuff. I'm not really sure. With the last act (or two) to go, I'm already at 18,000 words. Not really sure what to make of that, either.
Perhaps with these longer acts I can revisit the idea of posting each act individually.
