An entertaining sequence as the rider, by grimly hanging on to the girth rope, strikes a series of inverted poses without actually hitting the ground.

All of them have been nicely cropped. The second image is a wonderful study of the bull rearing forward, with just enough motion blur to show its speed, and the old bloke watching from the pens.

The images seem a little overexposed. You have edited the fifth image to make the colours richer and the background darker. This could done with all the images to make the action more dramatic.
