Welcome to the forum, and congratulations on the new camera.
I like where you placed the eagle in the frame, and you were dealing with some fairly harsh light. The only suggestions I would offer would be a) try to get closer to the subject (or get a longer lens, as you mentioned), and b) take lots and lots of pictures.
Birds in flight are difficult to photograph and your ratio of misses to hits will be high.
Good luck, and keep posting images!
P.S. You might want to tell us your name -- it might be easier than "Wapsijims".
