Easy to say, but hard to do. Shoot from lower down to eleminate the cluttered background. Good shot of the bull, but it would have been nice to see the rider's face.
Whooaaa! I get chills just watching that. Nice action shot. Expresses the theme well. I would've cropped a little tighter to get rid of the white sky and perhaps B&W would serve this shot seeing as the neon's are a bit distracting. My rule of thumb is usually that if the colour doesn't add to the theme of the picture, I make it B&W since it's less distracting and helps focus attention on the theme - personal preferance. Good luck.
Excellent Shot. Love that bull's eye! I really like the fact that all the spectators are focused on the Bull & Rider. Nice composition. The slight blur on the rear end of the bull and rider gives just enough sense of movement for this shot. Well done.
