Here is the EXIF for that last shot:
# Exposure Time (1 / Shutter Speed) = 1/10 second = 0.1 second<--------here is your problem
# Lens F-Number/F-Stop = 56/10 = F5.6
# Exposure Program = manual control (1)
# ISO Speed Ratings = 100
Your shutterspeed should be much faster. (larger number on the right) You are letting way too much light in. The EXIF also shows that a flash did fire, so I would check on that.
Are you hand holding?? I'm surprised that the shot isn't blurry. I must be horribly shaky because I have to be really careful about my shutter speeds. The other shots look pretty good for SOOC.
