Not sure if I understand the question, but I will try my best to answer.
As long as the work is original and your own, anything goes. Posters, flyers, etc. Just a graphic that depicts something about BandZ!
I am not sure what you mean by logotype. The logo they have can be used in the graphic, but you are also free to be as creative as you want!
If you aren't sure, take a look at some of the previous contests :)
Nice, i though you needed something like and advise of your brand with the logo included, but if i can do anything i want (under the rules you posted) then excellent! i will try!
thank you, any doubt i will ask again anyway!
Yeah, just a short description, link to website and your design. A little explanation on why you picked your graphic, just so we know your thought process.
Again, previous contests are a great reference point. Maybe refer to winners announcement if you are curious to see what kind of submissions have won in the past.
Good luck!
