Your aperture was 5.8 and your exposure time was 1/50. You shot in program auto, I would suggest shooting in aperture priority. The biggest problem with the picture is the flash, typically you should avoid using a flash with the style of camera you're using. You also want to use a manual white balance setting.
- Adjust WB to preset manual
- shoot in aperture priority with the highest f number while still maintaining a fast enough shutter speed to prevent hand shake and motion blur.
- Flash off
- You can bump up the iso a little and adjust the exposure compensation a little in the negative to get a faster shoot while maintaining DOF.
