Angel 33
This is angel 31 edited in Sketchbook Pro to change the color.  How to change the color of an object in Sketchbook Pro.  By using the lock that is on each layer, I was able to change the color of each layer without changing the brush strokes.  All you have to do is lock the layer and paint the new color over the old color.  This is quick and easy.  A whole new look to the picture in minutes.
