As the genre we have chosen is indie/rock I had a look a some previous album covers such as:
- The London Suede - Dog Man Star, Suede
- Train - Save Me, San Francisco, Drops of Jupiter
Using these helped me when creating my own, they do not tend to be very busy (words and images are kept to a minimum) and are not extremely colourful. Oasis is an exception, they're covers are a lot more busy and use bright, bold colours.
