For this image I had some difficulty selecting all the parts of her face. I used the magnetic lasso and quick selection tools, and the paintbrush to add color to her lips, hair, and skin.
I also used the selection tools to select the parts of the monsters body and to color them green. I tried to select the "spikes" or whatever you want to call them and made them a shade of purple with the paintbrush. I messed around with the hues and saturations of the green.

Next I painted the rocks and the sky using the selection tools and the paint brush. Lastly I painted the ground that the girl is sitting on a light yellow.
I also used the dodge and burn tools to make the sky and rocks look more realistic.
Problems I had editing this picture:
- Getting the selections to be exact
- The worth 1000 in the bottom left hand corner
- Getting the colors to look perfectly realistic
