rookie2, glad I could help out with flickr.
As with the composition, you have definately come to the right forum on getting advice from various people at various levels of background and photog skills. I am myself I newbie, so I would take anything a say with a grain of salt.
Not knowing what was on either side of the tree, I would have shot the image landscape, and place the tree more to one side. At the moment it really fills the foreground.
Best advice is take heaps of shots with different settings, setups and compositions and then analyse the results at home. Post a few pics up for critique here and see what the wise heads say.
HTH (a little atleast)
