I love the Y shape on the lower wing made from the shield tiles and L tile (which: smooth L??? whaaaa). Also the trio of quarter circle tiles in light blue, medium blue, and black
I like the texture pieces on the branch and the little flower that's shooting off of it
I like how the pillar is constructed, using those slight angle technic pieces (and Fun Cool Bar pieces to interface with it!) to tilt it back subtly, displaying the butterfly perfectly
I adore the bee, with its minifig wings (radddd) held together with studs-with-bar-holes (these are sooo cool) and a bar-clip, little egg abdomen, and that bucket handle(?) for antennae. It's so simple and small and good!!
