A series of retouched illustrated images of a silhouette of a rocket jetpack man flying in the sky at sunset. There are a range of positioning of the rocket man to suit your needs. Medium distance composition. The rocket man is an illustration put on a background image of the sunset. The rocket man illustration is an illustration that I drew in photoshop. You will see that it is just a flat shape with no tone or detail, but because it is a silhouette against the sky, it works well. The illustration is a traced illustration from a photographic origin and I took the original photo so I understand that I am the sole copyright holder. I have attached it for you to view in the releases upload as requested.
