Hi Mike
Good efforts - its not easy doing selfies!
#1 - its to dark to me, far to dark - re-visit your light set up, maybe just use some classic sets as available on any internet search.
You look in focus - but your wife isn't, her eyes and face are soft - revisit your aperture setting to give greater depth of field - or your shutter speed if its movement related.
#2 - bit of a portrait rule broken, side on profile of your wife's face really doesn't flatter the nose, ask her to try and turn towards the camera even more until the nose outline is covered by the left cheek.
To dark again for me.
Right idea to start with getting the tattoo photographed though.
- keep experimenting, its a great way to learn!
kind regards
Ian
