Oh ok, as long as you're just playing.
While you're playing, knock the ISO back down to 100, move the EV (exposure comp) back up to 0 and your WB to AWB.
Your ISO setting of 400 is introducing a lot of noise (grain) into the shots. Lowering the ISO will reduce the noise.
Your camera should be able to handle much higher than 1/400 shutter speed, btw, so I can only imagine that you were referring to the ISO setting.
Seriously, a good way to learn photography is to "play". Since digital is so cheap, you can go out and shoot all you like while changing settings and then looking to see what happened later.
The easiest, most important and biggest way to change the way a photo looks for settings are aperture (f/#) and shutter speed (1/###). Throw the camera in AV mode if it has it, manual if it doesn't and play around with those two settings. AV mode will let you change the aperture and make the camera automatically adjust the shutter speed. A small f number (ie: 2.8) means the iris in the lens is wide open letting in a lot of light which means that to properly expose the shot the shutter speed needs to be fast.
Vice Versa a big f number (22) means the iris is very small (think pinhole) and the shutter speed for the same image needs to be longer (to let more light in).
These two settings interact with each other and mainly control Depth of Field , or how much of the image is in focus. Small F number= shallow DOF. Big F number= lots in focus.
