Well, if this is the look you were after then you succeeded, well done! Rules are meant to be a guide and you certainly can break them as you have done in this self portrait. The viewer sees the catch lights created by your “on board flash” however, you have two additional lights that are acting like key lights. We see both the right and left areas of the temple lit with the same intensity light. In general, portrait lighting should be believable as we would see light on a subject in a natural environment. In other words we have only one sun acting as a key light with all other lights supporting the key light. This creates a natural or believable image similar to what the viewer would see outdoors.
I see the ears, hands, and neck brightly lit against the dark background which leads me to focus on them. Consider choosing a proven lighting pattern such as loop, Rembrandt, narrow, broad, or even split for a dramatic look. Remember the eye will always go to where light and dark meet.
Lastly, the image of the brothers is nice. I think the younger tike looking up at his older brother is a nice touch. The right arm on the older brother is blown out and I would pay close attention to the hands on both tikes (awkward). If your camera has highlight alert (blinkies David Ziser) consider using it as a guide. I think your self portrait is interesting and different and that may have been your intention.
