Acrylic painting of my Grandfather

From a picture of my Grandfather in the '70s, I drew the painting you see below. Here he is in his 30s or 40s. He has his tongue stuck out and stomach exposed, as he usually does (even to this day).

The painting was done several years ago, presumably 2007 or 2008. I highly doubt it, but I may have even painted it in 2009. I used Acrylic paint, and the size is 10x12 inches. 

As of now, this artwork is one of my few completely paintings. I hope that changes in the next couple months and in the upcoming years...
