With digital, there is a general expectation that you will have to do at least some basic post-processing to get the best results. Everyone has their favorite photo editing software; I won't go into that beyond saying that there are some very good free software packages. Learning how to make some basic adjustments will help you to produce results more to your liking. I took the liberty of making a couple simple adjustments to one of your photos above - I hope you don't mind - to show you what I'm talking about. This is literally three adjustment processes that took about one minute to complete.
At the risk of thread-jacking, can you give me the five-cent tour on what post-processing you did to that? I've got both Gimp and Digikam installed as well as the Nikon software that they offer for free, but all I've really done is a little cropping here and there and format conversions.
