Clarity challenge April 2016 - Masking

Last minute as usual!  I did a lovely card with a bunny but cannot find it!  This was the first card I did this month for the mask challenge,  before the bunny!

Very simple masking the hills in a rainbow of colours and the silhouette butterfly tree.  The happy Birthday was stamped onto a waste piece of card, but thought it added interest having the touch of bronze.
