Two crappy example shoot . but trying is fun

Would be nice see really challenging shots examples with A9 ,not landing or raising ones ,really flying ones.
Even dunno if you can evaluate how good camera is from examples . its more skill than camera .top shooter could do good pics with what ever camera.
And it depends shooting style what camera is good for certain people i believe.
