This FAQ clearly explains what "obvious" means for our purposes.
https://logotournament.com/help/designer/151The brief in this contest has a few design methods / concepts in the one visual image that gives you a clear idea of what the client is open to seeing.
BOW logo
1) serif font (Trajan is the one used in this contest winner - do I need to say how common that font is?)
2) ALL CAPS main text
3) iconic element fused with text
This is all in one visual logo from the brief. Does it not make sense that these concepts all together (or even one of them) in your logo is an obvious idea? Therefore it is obvious throughout the contest?
Maybe you have some trouble you clearly undertanding the FAQs?
If so, please review them and ask me questions in public or private. I am happy to explain more.
