Self portrait - Intense concentration!

Needed a photo for the Alphabet Challenge - I is for Intense. I first thought of taking a dog gazing intently at food, then realised I was 'intensely concentrating' on my OU study this morning so I took a self-portrait. It took a few attempts using the self-timer but I am actually quite pleased with this one.
It broke my concentration - so I put the books away until tomorrow!
