Am I doing something wrong? Sony A57

Thanks to everyone who has replied with comments and help.  I didn't want to post the original with the EXIF because his junk is out.  Anyways.

Here's the info.

Shutter speed: 1/40 sec

F stop: f/3.5

ISO: 6400 (I'm guessing this is where things went wrong)

Focal length: 18mm

Here's another picture, with the same effects, probably even more exaggerated.

Shutter speed: 1/60 sec

F stop: f/3.5

ISO: 3200

Focal length: 18mm
