I know what you were trying to do in the first picture but as mentioned above there was no real subject. I know how hard it is to get a good angle on aircraft, especially if you are like me and have no access to the ramp.
I would say use these two examples as something to strive for, I also have Sony camera....your file hints at that, and if you email me direct we can go through some settings?
You will see that the first one is more of a recent tail shot but if you have the Appature high, like i can only go to 8.0 on my 717, and set the shutter speed around 5 seconds... you will get bright lights like such. In the second picture there I tried to focus on the two asian aircraft, the 777 is getting most of the attention but allows for another aircraft into the picture.
As far as your second picture, its just needs to be rotated and should be accepted... I think there is an aircraft wing in the picture as well.... were you on an aircraft at the time?
Good luck with the night pictures,
