The other thing I’ll mention is that I’ve found that my camera has a grid overlay setting which really helps in keeping the pics level instead of looking like the aircraft are taxing/landing uphill or downhill as I found in my early shots, so if you have one on your Cannon which I’m sure you will then I would advise using it to help keep things level, which you don’t do a bad job of at all but it can save you time when taking the photo rather than “missing the moment” trying to get the level.
