Have you attached any materials for the cover because you mentioned "materials provided" in the brief.

Yes, there are four files. Others have already used them so I know they are there for you.

oh No! I was working on the design and it has just finished I was going to send my design
but as you selected the winning design I can't submit my design anymore :'(
Would you give me a private mssage and give me a chance to take a look at it? or possibility to extend the project deadline?
I spent lots of time and effort working on it.
