OOTD: Notice Anything Different

Do you notice anything different with these pictures? I was very thrown off today taking my pics in overcast grey skies so I started playing around with my camera settings. I usually ALWAYS shoot in aperture priority mode with a flash and today I somehow ended up in shutter priority mode with no flash. Am I crazy or are the pics sharper than usual?!?! If any of you shoot with a Nikon, I would LOVE to pick your brain. Unfortunately 99% of the people/photogs I meet shoot with a Canon. One of these days I just need to take a photography class already!!!
