Can you link to Clint's model?

Thanks.

A few more things to adjust:

1. the Copyright/Attribution Notice section should contain proper credit for both Clint Bellanger's model and freelikegnu's model (and yourself if you want), but "Same license applies as Clints" is not proper attribution by itself. See https://opengameart.org/content/faq#q-how-to-credit (also, the statement is currently inaccurate; this cannot be the same license as Clints. See below)
2. Becuase this is derived from two other models, the license must be the license common to all derivatives, which is CC-BY-SA 3.0 in this case, not CC-BY 3.0. It is possible freelikegnu only specified that license becuase that was the common license from Clint at the time (Clint later changed it to CC-BY 3.0) so if you ask freelikegnu if he is willing to change it to CC-BY 3.0, then this can remain CC-BY 3.0 as well. In the meantime, the license here must be changed to CC-BY-SA 3.0 to be compliant with the derivative chain.
3. Clint Bellanger and freelikegnu did not collaborate with you to make this model. You derived this model from their asset, but that isn't what the "collaborators" field is for.

Let me know if you have any questions about this. I'm always happy to help. :)
