I digitially added colour to a drawing yesterday, and I am quite pleased with the results! I've never altered any of my work digitally before, besides photographs, but I decided to see what I could do with photoshop. Even though I was only using photoshop at a very basic level, it served its purpose well, and will certainly go back with other drawings to alter them, as I found it very satisfying to work this way. The two pictures I have posted show the image before and after.
