My first few trips with my 400D

Hi, this is my first post on these forums, but looking around, I recognise many other members from other forums. (you may know me as either Dan380, TheDr2 or DanLTN)
Just a quick about me: I’m a 16 year old aviation Photographer from Hertfordshire. My local airport is Luton, but I make frequent trips to LHR, and have been to LGW and LCY a few times. For about a year I was using a Panasonic FZ7, which was a very good Point and shoot camera but wasn’t really up to standard, so this christmas I treated myself to a Canon 400D, and these are the results from my first trips!
Enjoy!
(Sorry some of these are really soft, it’s the fault of the site I uploaded them to)

December 29th, at the Bridge, LTN.

(This was actually the first ever shot I took with my 400D)

December 30th, at the Crash gate, LTN. (Overcast, so I tried some slow shutter speeds)

January 6th, LGW. (Very dark for the arrival shots, right ******s to edit)

Hope you enjoyed! Any feedback appreciated!
