Hi, I'm a scriptwriter in training and although I'm learning to write for TV or Films, I have been reading comics for some time now and I am very interesting in writing comic books. Where do you thing I should start my training from? Some websites, books?

Well, unfortunately there really aren't that many books on writing specifically for comics:
The DC Comics Guide to Writing Comics [Paperback] by Denny O'Neill
Writing for Comics with Peter David (Writing for Comics & Graphic Novels)

Writing for comics by Alan Moore
