Some people have it, some don’t.
Get “How To Draw Comics: The Marvel Way.” Study it. The art is old school, but you’ll learn the fundamentals of comic drawing there.
Then study up on pencillers like: Art Adams, John Byrne, George Perez, Rob Liefeld, Travis Charest, Marc Silvestri, and of course Jack Kirby, Steve Ditko, and Frank Frazetta.
99% of all comic artists start by pretending to be their favorite artists. Try to draw like these people. In a few years you’ll have ‘them’ down pat, and you’ll begin to understand the reason why they draw how they draw. Then you’ll be able to find yourself.
In the meanwhile, if you’re interested in comics find a position in the industry that you can work as. An inker, colorist, letterer, writer, etc. You may find that while you’re a C+ penciller, you may just be an A+ inker. This is the story of many of history’s great inkers. They thought they wanted to be a penciller, but turned out being a remarkable inker instead.
