The first is an ACEO original of another Star Trek character, Kes.
Kes ~ Star Trek Voyager
And the second is another digital painting in my One Hundred Humans series.
Human #9
This digital painting was created using just my finger (still waiting on my new stylus to arrive!) and several of my iPad drawing apps. The first one I used was Paper to lay down an under painting. Then I moved it over to Brushes and finally to Sketch Club for the finishing touches. Below shows a progression in the various apps.
