So, Just out of interest, would anyone actually consider using this model/texture?
If I were you I'd release it regardless (if it's 100% legal). Even if a majority of people did not like your work (not saying they wouldn't) it's worth letting even one person get to use it.
I think way too many projects end up dead and abandoned because their work isn't released when they quit. Even if it's not up to some standard or if it's incomplete I'd say it's still better to release if someone else can continue it in the future or get some use out of it.
