Not a bad pose at all Rene. I like it.
I think it only needs a very subtle tilt in the Pelvis and hips.
Bill Horan once mentioned that the relaxed poses are much more difficult than action poses, but I do not think you scare away from difficulties.!
Anyway, I suggest looking at Mike Good's work. He is a master of the relaxed pose IMHO.
