Just this sentence shows you're off to a good start!
A flash can be useful, mostly when you take it off the camera (or at least bounce it on a wall or ceiling). After all, photography is about light, and as the creator of the image you're entitled to take control of the light.
However, using the camera's flash, while useful in some circumstances, almost always degrades your image. In this case, you did very well, especially for a first shot. The composition, depth of field, nand lighting, are very good. I'm sure you will learn and improve even more as time passes.
