I've been talking with Arcanthur, and I think we're going to be taking a swing at a major overhaul of Serenity's appearance.
Frankly, while I can make do where needed in the gfx design department, my strong point is more in the functionality side of things. This makes me feel like Serenity is a very powerful skin, but still lacks the overall look of something as cool as (IMHO) it is.
That said, we have begun scratching out heads in an attempt to work out how to keep all of Serenity's functionality while making it look...erm...prettier.
Nothing has been put into code yet, but I though you might be interested in seeing the initial ideas. The end result is what I would call a fusion of the current Serenity style, Aeon, and a few design ideas that Arcanthur has had in the works for a while.
There's only the one ss right now, but I suspect that things will go rather quickly once we get rolling on this thing.
