Thanks for the originals. As regards the first shot, I'm afraid the original is way too dark. One look at the histogram shows everything on the black side. And also the original is sharp. Check your in-camera settings and try to leave the sharpness at neutral if you can. However I think this is better but still unfortunately not anet quality.
As regards the second shot, same thing again. The histogram is all over the place on that one. I don't think it can be improved enough for anet although I didn't crop it so tightly and a great shot to keep for yourself. There are also a few dust spots on it too.
The third shot is my favourite and maybe ok with better expert editing - I really like it. Here is my attempt although there is some kind of mark on the runway I noticed.
Keep an eye on those histograms and check the camera settings for optimum shooting.
Hope this helps.
