What's Missing?

Poor Kermit, always the model....even in the fairy set! 

It's been a long weekend.  Some days I'm just more creative than others.  My rocks turned out great (can you tell that I made them?), but something about the set just isnt' working for me.  The white pond will soon be replaced with the black mirrored one, so that's not it. 

So I need your help!  What's off.  Is it the background, too light?  Is it the greenery, should it be more ivy like or brown ground coverish?  I just can't put my finger on it.  So look at it, picture a cute little fairy sitting in Kermit's spot with a glowing wand...and maybe you'll figure out what's just not right.
