I think you have the start to something nice down the road. I would ( if it were mine) do a few tweaks.
#1 in the picture shows a U shaped image. Somehow not really pleasing to the eye. While it does depict motion and energy it conflicts with the lower trunk and some of the lower branches which indicate downward movement and the one in question shows upward movement. I think for the purposes of aesthetics and to be polite
that part of the trunk at the very least needs to be either cranked down to the back just slightly higher than the branch right below it. This would give more depth and and rid you of the U shaped trunk split. The other choice and probably the better would be to rid yourself of that trunk and create a Jin
#2 In keeping with harmony of the tree, a slight adjustment to the upper foliage on right hand tree. I think placement in a little closer (down and towards the front) to the composition would suit it more and fill in the void that #1 created.
#3 Is in keeping with #2. The upper right hand trunk has a bow in it, a drastic right hand curve. This to me is in conflict with the rest of your composition. If the top of the right tree was brought down as described above the curve could be made more convincing.
I think your on the right path, take my suggestions for what there worth. Sit back and re-evaluate your tree and pick out what conflicts with each other in the tree. In a windswept, flow+ movement +harmony is a key ingredient to sell the image. A convincing windswept is a very hard thing to achieve. In my opinion probably one of the hardest styles to do correctly in bonsai. Keep at it
