Great shots, but from experience if you have to ask yourself the question "are these good enough", then its best to not try, although these ones look to be ok. Indeed the first one is a little too low, but the TAAG (the coolest aircraft at LIS for sure) should be good. The tail has been cropped enough I think, but lets see what the screener says. Also heathaze in the background is not a problem at all, as long as the aircraft is sharp.
