Back Panel Ideas

When thinking of how to design my back panel, many ideas ran through my head. Some of these were:

• Shall I use an image of sky as the background to relate to the front panel? However, I did think this would be a little over the top and would take away from my front panel.
• Shall I use a plain colour related to the colour scheme? I felt this may be more appropriate as a plain colour related to the colour scheme would follow with the theme smoothly, but would also create a good base for the text to go on. On the other hand, a totally plain background may look too boring and unprofessional, yet would continue with the natural theme.
• Shall I create a subtle pattern to accompany the plain background? This may look quite good as the text would not be masked by too much detailing but would not look too plain.
