We must have a common wavelength. I questioned the arms from the start and it turns out we don’t like them for the exact reasons you cited. I’ve figured something out using the forms for slats the arms and made a new bending form with a shallow arch for the leg. I will post that and see what you think.I'll bet the wood is Cypress?
My "designer" suggestion is to raise the curved arm up at the front so your whole arm has more support.
As it is, your wrist and hand will droop off the arm rest, so not so comfortable for long periods.
And it will be easier for "old folks" to push out of the chair when getting out.
