You're getting good.
Your exits from the round loops aren't full height -- technically these aren't supposed to be judged, so technically you can relax and shorten them, but I'd go ahead and stay on the loop until the plane is at the top.
If you're going to err on the hourglass, make it narrower rather than wider -- this makes all the turns easier. But everyone tends to make it broad. Because you're intersecting the lines at 45 degrees rather than making a rounded-off corner there, the base is actually smaller than the base of the triangles.
But that's nit-picking.
