One thing to keep in mind is that photography, as many other activities, depends much more on how much you like it and and to keep improving than on equipment or technique.
The quality of a photo is much more related to what (and when) something is being registered than how it is being recorded. It's the photographer way of seeing the world that counts.
And "seeing what and when" is something that not everyone knows intuitively but many can learn by doing or studying.
My point is that now that you have a camera you are ready to go. Of course the more you study and practice, the better you will be. And surely there are cameras with more fidelity than others (imagine an old phone camera versus a modern and expensive camera).
But once you reach some level of fidelity (which most if not all cameras in the market already did), what will make a "good" photo depends much more on who took it (and who will see it) and what was intended, even if non consciously.
As Stan Rogers mentioned, you will keep improving as long as you keep open to learn. If you really are interested in photography, you will learn to identify what is a photo that you like and which ones you don't.
Focus on the differences between them. Try to learn from what worked on one and what didn't work on the others. Try to find what took you to take some photograph and how you would like it to look like.
That don't depends on the camera, but on your view of the subject (and the world around it). At first you may not know what subjects attract you more but as soon as you start paying attention to the results, it will be easier to know what makes you happy or not.
Since you are considering using the camera for travel, experiment with the scales for example.
You can start by seeing the whole scene around you and trying to capture its mood and presence. Notice the sky, the landscape (nature or not), the geography, the architecture, the streets etc. Learn how changing your orientation or the zoom on your lens impact how much can be seen at once and how different things appear on the picture.
Or you can start by seeing what happens closer to you. Notice the room you are, the people around you, what is happening and what is about to happen. You can be at a festival and try to capture the energy of the dancers, or you can be walking down the street and try to capture how people react to a barking dog. Learn how to separate the action you want to register from the background (by moving yourself or changing your zoom) and learn to anticipate what is about to happen, so you can be ready to register it when it happens.
Another option would be to start seeing what is really close to you. Notice the books on the stand, the textures on the rug, the way light reflects on glasses, your own reflection on a store window etc. Learn how to focus on an specific part of the subject and how to understand what attracted you to it. Learn how to use light to enhance or subdue parts of the scene in order to change the viewer perception of it.
As you see, there's a whole world of experiments and learning ahead of you. The examples above are just that, examples by someone. Don't take them as guidelines, but just as a way to see how diversified can be photography and notice how little mention of the camera capabilities were made.
