would have been a much better shot of any of the subjects would have been in focus...the point of focus appears to be the womans hairline...the eyes are paramount in a portrait. In one such as this, it's preferable to use a smaller f/stop like f/11-16 to get both the subjects faces in focus and to avoid the narrow DOF...just a hint.

Also, just my opinion, but...other than 'period' pieces (old fashioned types) it's just best to stay away from sepia toning, it's more preferable just to go B&W or stay color. In my experience, they just look better/sell better/do better...

The image is on-topic, and the pose is good, just needs some fine-tuning to be 'great'...GL Author
