A nice start Matt, some very nice colours and patterns there.
One rule I keep in mind when shooting is the 'rule of thirds' which helps you visualise and frame your subject for a more appealing and interesting view.
I like the viewpoint in the last one and the patterns in the third one.
When shooting flowers try getting an unusual angle or a viewpoint from down low rather than shooting from above or directly across.
This will add depth and extra dimension to the shot.
