I had a look at the getty shots and think your's are much better.
There are come nice stadium landscapes and some try shots on getty, but they seem to have too high a vantage point or aren't that sharp and generally lack the 'pop', 'xfactor' - that your's possess. Your's look much better angled from pitch level, and the colours are mindblowing, and they are much sharper.
You're doing a bit more than OK!
