Birthday card for my mum

It's my mum's 60th birthday next week and I had already bought her a card from the Quire Publishing collection some time ago. But since she's giving a birthday party in her garden I decided to make my own version of the card with a few adaptions.

This is a quick photograph therefore the colours aren't quite right, to give you an idea: it's a white background.
The text on top is "Happy 60th Birthday" in Dutch
and the (very unclear) decorations in the tree are glass jars with either a blue/yellow ribbon or yellow stars on them. It's a decoration I already helped my mum create for the actual party coming sunday.
