took a random fire risk photo to use as a background layer, took a dragon photo, used an alpha channel to select just the dragon head, dragged the levels right down to get just the black silhouette, took a flame logo, used transform and warp to get the right shape, took the sign photo, cloned out the existing warning sign and dragged on the dragon head and flames, flattened the sign image and brought it into the background. Had to extend the sign post, then using the using clone tool created shadows on the grass.
