They're all very nice shots. I especially like the tiger shots. Great colors.
One comment though. It looks like you went a little too far with the contrast, losing a lot of shadow detail. I suggest trying to shoot with some +EV compensation to get the details from the shadows. If you shot RAW, it shouldn't be a problem doing it in PP as well.
Great job.
