I had once joined a photo critique class led by a professional photographer, bringing a few images that I felt represented me. When it was my turn, his response was, "It's incomplete." My heart dropped for a second before he continued saying that he felt the image hadn't yet reached its full potential. He did feel, however, that my images showed a "joy in nature." That's all I needed to know and it's something that continues to drive me to improve my photography.
