Too much to to say without some specific questions.
Regarding your shots.

#1 - Tilting a photo just for the heck of it is more often then not - not a good idea. All it does is make the viewer tilt their head. Tilted horizons can work, depending on the balance and flow in an image.

In general -
If you really want to learn your camera well and become a good photographer, take your settings out of any kind of auto mode and stick with full manual for at least a month. Read up about exposure, how ISO/Aperture/Shutter Speed effect exposure, and what ramifications there are to the adjustments. Find interesting subjects to take photos of - if only to keep you interested. Examine your setting later for each shot, and work out, or ask others, what went wrong, and what went right. Take lots of photos. Experiment. Have fun.
