Panorama

I was walking on our nearest beach in this week. I took this panorama picture when sun was setting. I used PhotoStitch to merge all those 5 shots to one panorama but I don't like the result that much. PhotoStitch didn't make it so well and I don't know how to correct its result manually. I used tripod to take these shots and I double checked that it was well placed before shooting so I think that those photos are good but PhotoStitch didn't merge them that well I thought. I used my Canon EOS 1100D and kit lens. I think I need more practise to make good panoramas. Click the picture and you see it bigger.
