Tareq,
These look good, I would agree with the comment regarding the horizon and straightening it.
One thing to consider, looking at your settings is that you were shooting at ISO 1600 and getting 1/1250 as a shutter speed. I would possibly consider shooting at around 1/500 or 1/640 and dropping the ISO to 800 so as to reduce the noise issue.
That said, I am surprised by the amount of noise shown at ISO1600 for a MK11n.....did you underexpose these and have to bring the exposure up in PP?
in fact i can lower the iso and the shutter speed, but i was worry that maybe 1/400-1/800 not enough to freeze the actions to get sharper results, but if you see that 1/500-1/800 are enough to get good frozen results then next time i will lower my iso to proper one and reducing the amount of noise then.
In fact all these are underexposure and i bring the exposure up, yes i did, and don't forget these are cropped shots which will show more noise than uncropped one.
