According the terms of service of this character creator, "Subject to the terms of the EULA, Daum Games Europe grants the User a free of charge, non-transferable, non-sublicensable and non-exclusive license for the duration of the EULA to: ... take screenshots and make videos of the CCM and its content, comment and publish them on the User's website, a third party's website, his or her employer's website or on social networks, regardless of whether this publication generates, or not, indirect revenues for the User or the User's company (including revenues from publicity or from subscriptions)."
So I think it's fine for our members to use their screenshots from this to make character face examples.
