I liked the variety of circles in the picture: the outer rim of the plate; the inner rim of the plate; the ice cream; whatever that thing (maybe a piece of dried apple) is on top of the ice cream; and the tart itself.
I also liked the contrast in textures: the smooth plate; the less smooth ice cream; the even less smooth dried apple (?) and the not at all smooth tart.
Also the contrast in colors: whites; off whites; yellowish brown; reddish brown.
