This is a podcast cover. iTunes requires it to be 1400x1400 pixels. The main focus text will say:
The Sports Peel
and there will be accompanying text:
with Paul and Danny
It is very important for the name of the show (The Sports Peel) to be easy to read, even at a fairly small size, since iTunes shrinks these covers very small.
Please consider what podcast covers look like shrunk down in iTunes while designing.
The Primary colors desired are: Red, Black and White. Your design can use any mix of these three colors.
The aim of this art should be to engage and encourage people to click on it. It should stand out in a crowd.
And most important, don't be boring!
