/ic/ - Artwork/Critique

Hey there, op! I can't even explain how grateful I'd be if you'd help me out with a pose I've no idea how to begin figuring out.
I've been wanting to take this somewhere for years but have never felt confident enough to move any further since I lack any sort of reference to guide me on how to start this pose, and don't feel confident enough with anatomy to fake it.
The pose is:
(1) The man grieving for his dead daughter as in the attached. And
(2) <In case I end up bringing the subjects closer to the viewer,> the same exact pose, but with you closer to the camera and the camera tilted ever so slightly down. So it's almost exactly the same as the first, but just a very little more of your back would be visible since it'd be very slightly more of an overhead view than the first pic, but still from the same direction.

Thank you very, very much for considering my request!
