@AngelinaKizz Very nice concept!
I agree with Robyn that there may be a more "extreme" quietness to express here. I also agree with Miram that the view of the character could be more dynamic. The combination of these brings to mind images of a girl lounging in bed with headphones on, eyes closed, totally chilled out, or maybe the same view of her reading, but zoomed out a little with her off center and showing her environment.
The loud side could similarly be shown in a more dynamic light - maybe she's jumping on the bed, totally rocking out.
Also might be neat to show her in her bedroom in both images at the same angle and everything, but it's only her pose that has changed.
This all depends on the intent of the images of course - it's totally different to design a spot illo over a full spread, for example. My suggestions probably are more applicable to a full spread.
Looking forward to seeing where this goes!
