Even in the early 8-bit console days, I loved to flip through the games' manuals and compare the illustrations to the pixels moving on the screen. I've always yearned to be that somebody and see my creations come alive. My style is a mix of fine-arts draftsmanship and contemporary illustration, with some manga gadgetry and art deco thrown in for spice. I was 13 when I began copying Arthur Adams' X-Men covers and haven't stopped studying other artists' styles and works. Any artist that's been around will tell you that half the work is looking at what approaches to art are successful and learning from them.
Styles fluctuate and grow, just like the artist.
Honestly I'm too damn busy to suffer from imaginative blocks. Usually by looking at what others have achieved I'm invigorated to push ahead. Surround yourself with success and you'll partake in it as well. It's a simple process. Mostly mental work and brain to pencil stuff.
