It might also be good to avoid putting in the bevel



until after the large fillet is in place so the filleter doesn't have to try and deal with the difficult juncture area there at the same time. And it may be good to make the bevel geometry come from from a cut by a straight extruded curve rather than a loft between 2 edges as it is currently.

Then with putting in the bevel after the large radius to round it off use a slightly smaller fillet radius on it.

I'm not 100% sure about these, just some ideas.
