The sicilian is a good opening to study as sort of a final test in king pawn openings. I (as well as many other chess instructors) don't recommend studying this until you've studied all of the other 6 options. I would start with 1. e4 e5 if you want somewhere to start. Maybe first start by taking look at the two knights defense which I should be getting to shortly. :)
