Fun fact, tagging more than 10 users is considered spamming so none will receive a notification.

Also, users are not comfortable with constant tagging. You will lose their interest very easily.

Only tag someone when their presence is a must. If not, using the appropriate tags is all that's needed.

I am glad you've provided stages to your artwork. Users prefer to see proof of brain to know it is your own handiwork so keep it up.
