After the sketch of the landscape I started to fill in the colors.  I usually work from background to foreground, so in this instance I started with the sky and made sure I had that gentle lighter value near the horizon and the gradual darkening up towards the top.  I then put in the Mountains with some dark blue, the grass with a dark green and the water with the sky blue.  As you can see I started to work some lighter values into the grass and mountains.  There is a small part of dark blue in the back of the water which will be the reflection of the mountains. 

I chose this picture because it had beautiful colors, it had interesting zig-zag shapes and I plan on having the mountains in the back suggest a sort of valley.  My art teacher has been stressing the importance of composition lately, so I'm doing my best to be aware of that.
