Damian McGinty when he was 14. I've definately got his youth, resemblence is close...maybe a cousin? Graphite in the 4x6 inch sketchbook.
And then there's George Donaldson again. Good facial likeness I think. The ear's not right though. Golden's liquid acrylics (payne's gray and white) in the same 4x6 inch aquabee sketchbook. I was surprised how blue this payne's gray is.
