Carciphona is a high fantasy webcomic/manga written, illustrated and published by me ^^ Set in an era where magic is forbidden, the story follows a young sorceress who, despite possessing more power than most could even dream of, could not grasp the simple peaceful life she longed for. But all this will change, whether she is ready for it or not. Start reading from the beginning.
Most good drawing, like any skill, is achieved through practice. Deviant ART is an excellent community where people have compiled dozens and dozens of tutorials on difficult aspects of drawing. I recommend, instead of appealing to a single artist, make use of the contributions many other great artists have made. If you see a particular piece of art that you really like, try copying it to break down each of the individual strokes that makes it so good. (Don't post it as your own art! It's just for practice.)
I haven't touched that drawing program myself; not sure if it's really useful without a tablet. I would like to try digital drawing software, but probably in conjunction with good old paper and pencil.
