It's my feeling that you want my comment about the technical quality that your new camera can produce.
I think you've captured a very captivating face. Crop it tight and absolute blur the remaining background and you'll have a nice piece of art. I don't think it has much chance as a portrait because it has no eyes, but as you mentioned it's a snapshot--and let me add that it could be a really nice image with the correct crop and background work.
Some of us are of the notion (me for one) that the post processing can be as much a part of photography as pressing the shutter button.
