I'm glad to see that you've finally put this up after all the peer-pressure. But since you're straight to the point, I will be too. In short, I've always loved threading with your characters. There's always something related to them OOC we can laugh about and that makes both you as a writer as well as your characters a joy to thread with.
But since you asked for constructive criticism, here's a few things I (sometimes) noticed. We haven't written together in a while and upon looking at your more recent posts these tips/critique points may be less relevant, but I'll stick to my experience so far.
The Great Silence: Your characters have (in my opinion) usually very little to say. I love the way you write, mixing your character's thoughts with small actions or observations. But sometimes I found myself having quite a bit of trouble replying to your posts, since 'In Character' there is very little to interact with. It could be that that's just in our threads, but again, I'm basing this off my experiences.
That leads straight to my second point:
Take the lead! I really enjoy it when you're the one in the driver's seat, and I think that's something you should/could implement more often. It doesn't have to be longer than a round or two, but I often felt like you let yourself be pushed away and react instead of moving the plot ahead. It could be my fault for moving too fast or 'seizing the plot' in my posts, but you shouldn't be afraid to return the favor and add your own unique plot development to it.
That about sums it up, I guess. Not much to say or point out, since your writing is solid in my opinion. Just keep doing what you're doing, keep having fun and it'll be a good read regardless!
