As a photographer and artist, you must always strive to evolve your skill and push yourself to continued growth. The moment you stand still to take a breath or admire the view, you will instantly fall behind. Don't get comfortable with your workflow. Stop using the same lighting set up you always use and try something completely different. Try a different editing technique, and play with features in Photoshop that you have always been curious about. Look up all the videos on editing and lighting you can. Do not stop even for a second. Your craft depends on your ability to evolve and change. I've learned a lot over the past year and a half that I have done portrait work, and none of that was learned by being content with my work or celebrating mediocre work. It is extremely frustrating when I see photographers that have been doing this for several years longer than I have celebrate their work that is full of technical errors, poor retouching, and bad color toning. You owe it to not only yourself, but the models you work with to evolve. Below is an showing the difference between one of my first model shoots to one I did last month.
