Inspired by the Elvis song of the same name.
A couple are heading off and walking next to a railway track. whilst a semi-transparent mother and father look forlornly on. So we have the optimism of lovers with an exciting future contrasted with the parent's sadness of losing a son.
Sometimes I get inspired by a simple song I hear especially if I can somehow relate to it.
I used deep shades of blue to capture the underlying mood.
