自我批評

自 = 丶 + 目 : Mnemonic symbol: a hand mirror, which someone uses to look at themselves.

The Eye of Providence (目) is looking at itself (自) in a handheld mirror (自) in the space station's bathroom (Ø4). It think it's indeed looking very good, since Zorro (z) attached a petal (丶) to its eye (目).

我 = 戈 + 手 : I (我) find Willy Walrus (w) lying motionless in the observatory's living room (o3), and there's a dagger-axe (戈) sticking right in his chest. I (我) try to pull it out while wearing a baseball glove (手).

批 = 扌 + 比 : Pocahontas (pi) bought a new bikini (比) and is wearing it in front of the space station (Ø1). Her fellow astronauts do not at all agree with her outfit and criticize (批) her heavily. They even go as far as to pull on her bikini using toy claws (扌).

评 = 平 + 讠 : Pocahontas (pi) saw a pan (平) advertised on an advertising column (讠) in the engine's kitchen ((e)ng2), but she is not satisfied at all, so she leaves her comments (评) on the pan by beating the pan over the advertising column.
