Overnight, I've thought about losing the leaf point. And, I've decided that it doesn't really bother me. Autumn leaves are not perfect. Neither is mine.
With regards to colour, my plan is to have at least one colour in each block repeated in another block. The penguin belly is the background to the heart. The yellow background, and the orange from the penguin’s feet will form part of the daffodil. Leaves from the daffodil will be used in the Christmas tree. Not every fabric will be repeated elsewhere, but one of the fabrics in the block will. This will hopefully give the quilt continuity across the months/blocks.
