I use the CC Photoshop but Adobe are thieves. If you're looking for something free to start off with, GIMP has all the main tools I use, mainly layers and bezier  curves/paths.

However there are cheap alternatives out their too, like SAI or Manga Studio.

Cheers, can't wait to see your art brightening the site!
