Something to consider:
-spar/web rivets 'appear' to be overdriven, a lot.
-rivet above the rivet/flange you are questioning 'appears' to be under driven and the flange doesn't look like it's fully nested. Address.
-2 rivets up - 'appears' to be set in an oversized or oblong hole. Address.
-flange dimples 'appear' to be less than crisp, a lot.
-if you keep your bucking bar on the rivet you won't scratch the primer off of your parts
Above comments realizing that pics can be deceiving.
Response to your question: many-a-flange has been removed and replaced with a new one.
As experience is gained skill usually improves. Rivet gauges can help in the meantime.
Good luck and have fun. Slow and steady as she goes
