I really like that layout, nice mix of turns and inversions for an invert. Some of the shaping looks questionable, but I'll reserve judgement until I see some more angles.
The zero-g is the only thing that, to me, looks like it may be a bit messy. Given the height of the ride, you probably don't have all that much speed going into it for the leads to be so steep. You should make it a little more rounded and less harsh (even though I don't exactly know if you can do that- it looks like it might be newtoned, but then again that's what people have said about my last 4 hand-built rides)
But like W-O said we might just need a different view, or to actually ride it.
That all being said I love the layout and the lesser-than-average inclusion of inversions. It's kind of original in a good way.
