Sakura Card Captor - Birthday card (WIP)

Here is a birthday card for a friend of mine who loves Sakura Card Captor and who got me started with watercolours.

I know that my watercolour is not wet enough, than I put too much water... So don't hesitate to give advices

I also know that some parts aren't drawn well enough (especially the stars), but I was really short on time for her birthday party :/

(Final version alone in available in my gallery)
