My very first inspiration, when I was about eight, was Bob Kane. If you've never heard of him, it's not surprising, as his fame didn't seem to follow his greatest creation, Batman. To this day, there's a touch of Bob Kane in my style, especially when I draw someone smiling. If you look at very old Batman comics, you will see the distinctive Batman Bob Kane smile.
When I glance at modern comics (which I only do in passing now in bookstores), I see the style of Jim Steranko. I was young when he burst onto the scene, and he changed everything. In addition to the way that he drew, I was amazed at the way that he composed pages. It was the beginning of understanding Graphic Design for me.
