꾸미다(vt, vi) here means "make up" or "spruce up". It refers to doing work to make one's appearance better. It is used with an environment (room, house, office) too in the sense of decorating to make the place look nice. 꾸민 모습 is thus "spruced up looks", or "artificially enhanced looks" in more formal language. Your transcription has an error in 꾸민 안 모습. It should be 안 꾸민 모습(unenhanced, natural looks). (꾸미다(v) -> 꾸민(a), 안 꾸미다 -> 안 꾸민)
