Not a lot wrong with these Glock to be honest. I'd say 3 is probably the best shot of the lot. The main thing you need to watch in football/soccer is:
keep nice and low with your stance - which you've done well in these
try and keep the ball in the picture unless theres something really big happening that grabs the attention,
crop tight to the main action, but not too tight that you cut off huge junks of the players bodies,
try and show the faces of the main players in the action as far as possible rather than backs of heads,
try and eliminate other players limbs coming into view in your main action especially across faces,
your positioning - start the game on the sidelines then move to either bye-line. Start of games usually has close action in midfield with lots of tackling which can provide great action shots. When the game opens up a bit more then you can move to the bye-line between the goals and the corner flag. Then you should get the goal mouth action. Its trial and error and much depends on the teams involved.
I think you've made a great start and with a little more experience and practice you'll soon be hitting the big shots.
