Wow...nerdgasm..
That looks AMAZING. I'm jealous.
But I see some slightly slanted brush marks. Maybe it's the angle though. Still bugs me but got to admit, it looks amazing!
Oh, also, just a suggestion. Sometimes it's not good to use too high of a grid of sandpaper if you really want a good brush finish look. When you use one really high like 2000, it becomes more mirror-y, like you said. But it all depends on what you want.
