I like how the contours are matched/continue on the doors above/below. I assume that is because you made up a large panel, planed it, and then cut it into individual pieces for the doors?
I've been experimenting with the rustic undulating head recently as well, which i recently got. I haven't been satisfied with the results though. One of the problems I've run into is that the contouring gets much less pronounced after I run a sander over it (RO90 with interface pad), so that what's left is more of the "suggestion" of hand hewing. But maybe I'll try to follow your lead in doing a regular pattern with the planer, as this would require less aggressive sanding to smooth everything out.
