I realise that you don't have the best of camera's, but the 1st and 3rd shots are fairly unsharp. I suspect that they were fairly long exposures and that there is movement unsharpness due to a slight movement of your hand. Try to keep exposures short if you are not using a tripod. The colours of thr 3rd one are also rather strange.
Thank you for the comments Helen, the first one was kind of a grab shot, the original doesn't look quite so bad but setting it up for internet didn't do it any
