Acrylics greetings cards

These are all my mother's work. She does most of her painting on the faces of small children at fairs and festivals, but I think she has been discovering new techniques recently and has been practicing, so it seemed a great opportunity to get her to do some greetings cards for the craft unit. What do you think?

The pink blobs on that last one are butterflies, note please. Hedgehogs coming next!
