Your light is in the exact center, a big no-no. Why? Because it makes your pic boring. Remember the rule of thirds and put the light off to the right or to the left with all the dark and you'd have a good pic. Good luck!
This photo has very little 'subjective' impact. "What" you choose to photograph is very important. It's half the battle. "How" you choose to photograph it is the other half. When you create a nice combination and balance between the two, you will have great shots :) - setzler
