Hi Wallace, your going to love your new camera and pretty soon wonder why you ever wasted your time with the point and shoot. I was in much the same position as you a year or so ago and this forum has helped me improve my shots no end. I liked your third duck shot with the single duck taking off or landing.
Did you get yourself any lenses to go with your camera. I bought my 70-300mm vibration reduction zoom lens when I got my camera and it is great for shooting birds and animals.
