Yes, That's the site! Thanks so much for the link. It's a plum flower? Oopsie. It's very pretty.

radstorm,

Your best bet, imho, is to use Tucan's Cherry in the foreground with the figure.

In the background use Daz cherry trees:

And sakura petals blowing in the wind:

Also...

Poser billboard cherry trees:

Or if you own Vue or Bryce, use cherry tree billboards:

And You could also use an existing Vue scene:

I think I saw a Vue scene put together with Mt Fuji somewhere....

Do you have a Mt Fuji DEM?
