Anyway, here's what I came up with:
I put the hills, moon and sky in first, then stamped all the images. Then I added a shadow under the castle, and coloured in the tree. I've left if without a sentiment.
I'm entering this into the following challenges:
Lavinia Stamps 'Any Colours You Like'
Friday Mash-up 'Watercolor fun!'
Loves Rubber Stamps 'Anything Goes'
