First time trying Digital Art and now I know why digital artists love their medium because they know how to use the software and can do so much with it.
I have always liked drawing with wild pastel colors and finish with a black pastel on top. Then use a needle to put put the image. Off course it is even more easy on a devise, when you don't get all the mess.
One of my girls with lots of patterns. The girl keeps in blue and purple and the background and sunglasses is kept in green, orange end yellow tones. I have always had a hard time using less color and this is my practice in keeping a more stringent color theme.
