Marvel Comics Pencil Drawings

How can I make my pencil drawings turn into great professional looking comic? As a Marvel or DC Comics?
What do I need to goto school or the degree that I need to get to be able to pencil, ink and photoshop my sketches into professional quality renderings? I want to work for Marvel or DC Comics, but how do I get to that level that I can give them a license? Thanks to people on yahoo answers in advance! Any information will be useful, as computer software to obtain or the name of any person or school to get in touch! It's my dream to be a real artist, but I'm stuck! Where I'll just have talent? How the pros do it? Is there anyone out there who knows the process of making a pencil sketch to a finished page in a comic book? If so, tell me what to do to get this done? How do they take a pencil drawing and painting it? I just do not understand that technology is not considering comics have errors in all. It looks very like the magic and mystery to me. I'm sure I could learn these techniques, if I knew what the commercial art schools for driving? Thank you again!
You may consider gifts in Joe Joe Kubert School of Art is an established writer in comics, and taught a large number of people improve their work and storytelling styles of sequential art. Be aware that Kubert only accept those with obvious talent, and he will do everything he can do to help her students are published. Marvel and DC will not look at portfolios of people who do not have a long list of publishing credits, then no matter where you study, be prepared to start at the bottom realative. Do not forget to learn a very good job, then you have a workday.
