Started working with layer masks now, this is a first serious effort at a decent picture.
Here are three versions of the same thing + the original picture which I got out of Ultra Fractal 5. I lifted the beetle and shadow from a stock photo by Xandert on Morguefile...
here:

...and altered the shadow a bit and generally tried to make it look like the beetle wasn't just 'stuck on' or 'floating'. I think I was fairly successful but it still could be better. So both positive comments and useful suggestions are all welcome.

The next 'project' should have something actually flying in it, off to start work now.
Thanks for looking!
