I came across this resource that aspiring comic artists might find useful. It's called The Best American Comics. They come out with a new issue every year and it is what the editors have decided are the best comics they have seen for 2009. I do not think the major comics will be in there, but sometimes it's good to look through stuff like this to see what is out there and what you need to be like in order to get noticed.
They also have many other subjects, as well. I have not gotten to read it yet, myself, but I am going to try to look into it.
