孤身只影

孤 = 孑 + 瓜 : Gitta Giraffe (gu) is currently the space station's lone (孤) inhabitant. To feel less lonely (孤), she drew a mosquito's (孑) face on a melon (瓜) to have somebody to talk to in front of the space station (Ø1).

身 = 自 + 丿 : Mnemonic symbol: a bodysuit.

Sherlock Holmes (sh) tries on his new bodysuit (身) in front of the encampment ((e)n1). To see himself better in his hand mirror (自), he uses a banana (丿) as a selfie stick.

只 = 八 + 口 : Mnemonic symbol: this character looks like something (a head?) on two legs. I'll just represent it by a cuttlefish (只). James II of England (zh) has been in the space station (Ø3) as the only (只) one for too long and went mad. He thinks he's holding a mandarin (口), but he's just about to bite into merely (只) an eight ball (八). On the top of his head is a cuttlefish (只) he mistook for a hat.

影 = 彡 + 景 : Maud Younger (y) wants to watch a movie (影) inside of the engine ((e)ng3), but only men are allowed. She doesn't bounce back but instead, being a suffragist, puts on a long, fake Santa beard (彡). She enters to find that the whole movie consists of a still frame of a bonsai tree, a landscape in a pot. Back in the days, the script writers were not so experienced it seems.
