Im a fairly good drawer ( well atleast i think so) but when it comes to coloring in and lineing my work on a computer i wouldnt have a clue how to do it properly ive only dealt with pixel art size of digital imagery. What i want to know is their any really good tutorials on lining your work using photoshop and coloring your work using photoshop or corel painter. The main style of coloring i want to know how to do is the following images off
