Very nice. I particularly like the 5th & 6th images. Love the low angle on the 6th. Some tips: if you have a long lens, use a wide f-stop and fast shutter speed for action shots. This will help isolate the subject and reduce distracting background items. It's hard to take shots at shows and get a nice background, as there is always so much clutter. Try and position yourself at shows where the background looks good and you get some nice side lighting - easier said than done. Most people will dislike cropping off part of an animal: ears, tail, hooves, etc. If you want to do an artistic crop like that make it very evident that that is what you intended and avoid cropping at joints. Light areas will draw the eye to them, so if they are on the edge of the image, your eye will be drawn out of the image. You want your viewer's vision to be kept in the image for as long as possible. Keep up the good work and post some more.
Thanks for the advice, the 6th pic I was trying to zoom in and just get the horse. I wish I would have got the tail but I still got a nice shot. I took some pics at a indoor show and it was hard to do action shots because I would turn the shutter speed up and the lighting would get darker. And if the shot was to close it was blury that's why I love taking shots with natural light.
