Noob in need of help

Here is a photo that I took today with f/8, 1/1250 and auto ISO which came out at 320

Have a look at the full res picture from the dropbox link and you will see what I mean about the image not being very sharp and clear

I used a canon 55-200mm lens at 200mm with my EOS 1100D

I have a steady hand so don't think its my hold, yet im still to test it with a tripod

But like I said before not all images are like this, some are crystal clear
