A month ago I got into manga because I wanted to make comic books with my own characters and settings. But prior to that, I have no real experience with manga or anime. So I'm asking for your advice. What's a good manga series for someone new to the art?

More specifically, I'm really into fantasy (Tolkien etc), and I love seeing different art styles. But anything really will do. So any comics or series that you recommend would be much appreciated. Thanks!
