Welcome, Minori. I'm so pleased Peggy told you about this community! We have great fun and some interesting posts on here!
Beautiful pictures and it is lovely to see a glimpse of your home neighbourhood. The park is beautiful and I agree with llewela, the flowers are pansies or violas, same family and lovely colours. You're right about how cute that duck is, love that curly feather it has!
But oh, the cherry blossom - absolutely beautiful! And the peach flower, too - thank you so much for sharing the pleasure with us all! Look forward to more, when the wisteria comes out, if not before perhaps?? (she says hopefully!)
