My Grandfather in WW2

I recently started trying out a new style of illustration. I've really enjoyed it so far and I'm looking forward to trying it out on a larger scale. It's mostly based on airbrushing and coloured pencils ala the amazing Drew Struzan, with a little bit o' brushwork thrown in for good measure.
This is the second painting I've done in this style and it's based on a photo of my grandfather in his uniform taken during WW2. He was in Italy during the battle of Ortona, where Canada played a pivotal role during the war. I'm pretty happy with the way this piece turned out and I like to think he would be too.
