Newbie contribution feedback

Hello everyone, i've recently joined from an anonymous lurker to a registered user

I've been tagging few pictures and I was wondering if i could get some feedback to know if I was doing it right before i might do unproductive contribution

Could you please tell me based on the few images i've started to tag if I'm doing good and/or missed some good practise ?

When should I remove the tagme tag (I don't feel confident considered the amount of tag that exist i feel like i might miss many obvious important ones) ?

Thanks for taking the time to answer me.

You're doing good for now, especially here when you correcting that cum on stomach mistag. Keep doing that.

Thanks for your reply and , is there a way to know if one of my tags was wrong and got removed ?
Any other tip I should know ?

you can check on the post's history tag at the bottom left.

There's also EventListener (topic #14747), though it's a bit of a dark art to set up correctly so may not be worth the hassle.
