During the process of cultivating one's own "style"--be it in design, photography, clothing, whathaveyou--self reflection is a must. Studying one's own work is not only humbling (I often find myself thinking, why in the world did I choose that pattern? That placement? That cheesy effect?), it's also a good starting point for development. You view your projects more objectively once you've let them age for a while. You're able to see the progress that Current You has made since Past You created that piece of work. Or, in this case, that series of work.
Of the many lessons I've learned through analyzing some of my older photography, one of the biggest is that, well, I take way too many sky shots.
This is just a fraction of the collection. Posting them all would keep you here for a good 45 minutes.
Such a realization doesn't mean that I'll never take another sky-centric photo again; the habit, after all, is still a part of who I am as a creative. But I'd say this is an indication that it's time to try a new angle.
What patterns do you detect within your own work? How do you develop them to keep from getting stale?
