I suppose it depends on how it is to be used and if the manipulation is acknowledged. I do like your owl and moon though. I tried similar tho I haven't got photoshop, but used a layering technique in a free program I have and produce this one...
The swan isn't in the original image - I chose one with a similar colour and wave effect in the water. As Eric used to say ' you can't see the joins'
But I think well, if I can do that, do I believe any photograph?
