that sounds really cool!
i guess, at least from my part, it depends. Are they just inspired or do they look like copies? Inspiration comes from many places and if they aren't carbon copies I believe it should be ok.
counts as canon based character? i`ve sketched 5 kitties inspired by AJR album covers, but i`m a bit hesitant to upload them...
EXAMPLE: (IC)
OG cover:
chara that i`ve made:
artofnessa i`ll make one character and show it in og post later, ok?
i think it still works like moodboard characters, though you’ll have to credit the cover in some way tho
artofnessa i`ve uploaded a pic of it as example!~
1st of all:
AJR YES, the design is so pretty and creative! I love how you used all the floating instruments as design elements
Second of all:
Mostly just what others have said. You're using is as a source of inspiration, should be fine as long as you make it clear the design was inspired by the album cover. You could do an offsite creator with a link to the album, or maybe put the album cover in the corner of the design's image so people can see it :)
