Welcome to the forum George. Lots of avenues exist to improve on results - from composition to post processing, and everything in between. Lots of folks on this forum are willing to share their knowledge and experience (lots of good posts on many topics can be searched for using key words). One of the best things to do is to really pay attention to the images posted here (or in books or other web sites) that you like and figure out why you like them: point of view, quality of light, composition, etc. Then learn how to achieve similar results by trying to emulate those images (trial and error, asking specific questions and seeking out those answers from all available resources, practice, doing self-evaluation, and more practice). I'm sure others will add more thoughts on the topic. Keep on shooting.
