Outside the office where I work we have a magnolia tree. I've always found it a bit difficult to get a good shot of it. Over the past few years I have tried several times, but that image always seems to elude me. Hence a single flower yet again.
Some skills are like riding a bike. Once you have mastered it, you will be able to pick it up again even after a long break. Other skills require that you practice them on a regular basis to be able to perform at a certain level, like playing an instrument or speak a foreign language. For me photography is in the latter category; it takes some practice to get back into the grove again.
