Yes, Rainbow put those bandages on 100% for aesthetics. And yes, those are all Rainbow's accessories Scoots is wearing and they're all too big for her. They're just having a fun little photoshoot doing cool poses.
Man I loved drawing Rainbow overconfident and arrogant.
I came across this German youtube video (an Easter Bunny parody) with a dope clubbing song (starts 03:25). But the main inspo for these images was the gorgeous lady singing the refrain and her absolutely stunning hairstyle (lady starts at 03:58 if you only wanna see her lmao) , which I immediately wanted to put on Rainbow. Plus I imagine Scoots would want something similar but needed lots of hair pins.
