I see what you mean, Deviantart puts the CC license message hidden away in the bottom right of each model’s webpage, so I’ve added the text in the directory gallery on the left to make it clearer - thanks for pointing it out!
When selecting CC licenses, Deviantart gives non-commercial as:
The licensor permits others to copy, distribute, display, and perform the work. In return, licensees may not use the work for commercial purposes — unless they get the licensor’s permission.”
So if you want to discuss using something commercially, just let me know using the “Send A Note” icon at Deviantart (https://skororu.deviantart.com/).
