Photoshop is great, and and a nearly indispensable part of web design and digital photography. It's really quite versatile , so I dont want to sound like am saying it's not the tool for digital art or illustrations. depending on your art style, you may benefit more from using Adobe Illustrator tho. In either case, you can still scan and import... or use the mouse or Wacom tablet to trace or draw freehand. I just feel like illustration wise, AI allows you to correct line work easier, change colors and be size-independent.
