Hello! Thanks for your message, I don't know what you mean by "resolutions for clothes art" but if you mean if you can use a custom image as an icon instead of the default character, yes, you can.
I attached photos.
The base plugin already allows you to change the 3 character graphics:
Face/Movement/Battler
Depending on the outfit chosen.
Commercial License is available when you use the full version of the plugin. It would be appreciated to add to the credits of your project: "Undermax or Maxii1996"
All the best!
