There are a couple of things to consider when shooting outdoors. The guys mentioned white balance. White balance is important, but most cameras get it right in automatic mode when shooting outside. What's more crucial in a scene like yours is the exposure. Look at your second picture. The majority of your face is in shade but your left elbow and leg are in full scene and the range of brightness between the two is very high. This creates havoc on a cameras meter. If you use the in camera meter to average the scene either the highlights will be blown out (they are) and the shadows not a rich, deep tone or just the opposite everything will be too dark. All of this depends on where your cameras meter is pointing at the time of exposure. A camera's meter is designed to average everything in a scene to an 18% gray tone. Every camera made does this. One thing you can do to get a better range of tones in a scene like this is to use a neutral density filter. ND filters reduce the entire range of brightness in a scene, giving the scene a more manageable tonal range. The other thing you can do is meter for your face. Typically, when the subject is properly exposed, the human eye ignores everything else around it. So expose for you and let the rest of the scene fall where it may and use a neutral density filter to reduce the tonal range.
