Thank you all for your comments!
Even before I released the shutter, I visualized the photo from a cinematic 16:9 perspective. So this is a full frame shot cropped top and bottom to fit that format.
At first I thought the forearm on the right a little distracting too. But when I removed it, the photo lost something. And then I began to see it as a part of the overall gesture. The "in close and intimate" perspective distortion works, to my eyes, in this case.
