Usually your OCS clothes are quite simplistic,so I recommend looking into Aesthetics [maybe on Pinterest] that'll reflect their personalities more !!
Oh I didn't see this !!! And aa simplicity in your style it v pretty but it doesn't really make the characters stick out
Ofc u don't have to change it if u don't wanna !!!
seek a better artist for criticism, if you want criticism many people that don't draw much will say it's perfect and it won't help. even i think its good
