You have been practicing choosing and blending colors.

To begin your painting,take the Hartman Creek photo of your choice, and use these new painting skills to create painted layers of the picture on new layers.  

I would advise everyone to paint an area until you are happy, and then create a new layer to start painting another area. The layers allow you to edit as you go without disrupting everything.

Review the last tutorial and pay attention to how he handles the layers of color.

When you are done, you will have a painted version of your photograph.
