One thing that you can do with long, thin branches that you can't do with short branches is to bend them into the arcs of a windswept...
I think quite a bit more arc could be had than is illustrated here. It doesn't take much to arc the main trunk at the top with less and less as you go down the trunk. The only rule is that since all the branches are the product of the same conditions, they have to look like they all belong on the same tree. The lowest left is almost flat, and all subsequent branches have increasing amounts of arc, however the arcs need to be very similar and trace each other. The 7 left branches need to have about the same amount of space between branches, which is to say, they need to be evenly spaced so as to reinforce the image of trailing in the wind without getting bunched-up in one place and loosing the grace of the windswept look. The upwind side has shorter branches that are upturned towards the ends, again, by about the same amount and it's important to keep the open space similar. Open space allows the viewer to see the branches' arc. You can't see an arc if branches are too bushy or the foliage interweaves together. Sideways or sub-branches follow the same rules of having been influenced by the wind, so clouds are flat-ish, but the continuing arc of the top of a cloud can flow into any open space, front or rear.
The front view is the golden triangle having 3 unequal sides: bottom is longest, windward is shortest, and downwind is intermediate. The plan view looking down thru the top is also a golden triangle: The front is ~flat and the longest, the rear of downwind intermediate, and the rear windward is shortest with the intersection of the two rears meeting approximately behind the main trunk, and all 3 peaking at the top of the main trunk. Think about that!
