I really like the design of this first piece. The way that the artist played with proportions looks really cool to me. Everything at the top seems very heavy and bulky while tapering inwards the further down it goes. And all the while it's doing this, it's still maintaining a kind of symmetry down the vertical center line. It almost looks like some kind of other worldly creature.
I like the second one because of the way that the artist used multiple pairs of hands to create the shape that we see here. It seems symmetrical, however, if you take a closer look at the hands on the bottom, you'll notice that the thumb is on opposite sides, thus making this part of it asymmetrical, at least in this way. The design of it is very creative and can entertain your mind for quite a while.
