Linework for a Capt. John Noble print/variant. The beauty of working on your own project like this, is sometimes (schedule permitting) you can just draw up some random image you see in your head, and then use it as you see fit for promo/cover/greeting cards; anything. Being the master of your own destiny is definitely the single most significant reason to go the creator-owned route (it sure ain't monetary!). For better or for worse, every single decision is yours.
PS- That's a Harley-Davidson WLA military bike that John's riding. Just love drawing this stuff.
