This has been a great challenge. First I cut out the butterfly and gave it three filter effects, edges (width 1, brightness 8, smoothness 10) stained glass (cell 5, thickness 2, intensity 1)
Texturised (scaling 70%, relief 3, sandstone)
I then gave the background three filter effects
stained glass (cell size 10, thickness 2, intensity0)
Craqulure (spacing 9, depth 8, brightness 8)
