I'm going to give a try next weekend, maybe using wind mod.
The particles tend to arise from the object, and the wind tends to direct the leaves in one direction, so the movement is not the same, then it also implies gravity, since the leaves must lose height as they lose strength.
In addition, the movement of the leaves must be asymmetric to be realistic, although it seems that they all go in the direction of the wind, not all of them move the same, since each leaf is an object in itself, and behaves like an individual independent of the others.
I don't know to what extent I can get this with the particles.
The solution I can think of is trees with much less leaves, if you put several trees together, you will have a lot of leaves flying with the wind and then on the ground; a few autumn decals, a good autumn soil, a few lively trees, and friend you already have a good corner to take the bride. LOL
