Visually speaking, the redesign is superb.It gives you an idea of what NG artists can do, and it's really top-notch.
Forum-wise, I don't see why the left part is so cluttered with stuff now, the level icon was always good enough for everyone-plus now it's way too small and rather pixely (yes, I know it's supposed to be like that, but it looks a bit low-quality compared to the old level list).
And about the userpage, it's not very good, practically speaking.
You have all the favorites, updates etc. on the right, but absolutely nothing on the left, so why did you put the stats on a separate page?Please put them back there, or at least give us an option to do so.
Now I have to switch pages every time I want to either look at my stats or just look at my BBS posts.
And, speaking of switching pages, a separate page for submissions that are under judgment seems superfluous as well.Again, more clicking that could be avoided.
Apart from those three issues, the rest of the redesign is pretty amazing and it makes the site look very modern.
