Yes, needs more Duke.
Timing sounds quite good to me, so I'm not gonna bug it.
As for the object placement, this is one of those beatmaps that sounds right on autoplay, but you'd have to watch the autoplay a few times to know what's going on. Once you're familiar with this beatmap it's great, but the learning curve is higher than normal and that's usually not a good thing.
The last combo before the first break also feels a little weird. The first of the two long sliders might be better off broken into little sliders to get a more consistent feel of that wavering effect (from the whammy bar?).
The drum rolls are cool though. This song is really fun to watch on autoplay. I wouldn't really bubble it yet - I'd like to see something done about improving the intuition of the map so there's less guess-work, but how that can be accomplished is a little hard to say. I'd like some more opinions on it.
