am i stealing?

ok so i’m an artist on instagram and i rly admire this one other artist. whenever i need inspiration i normally go to their account and take some of their ideas. for instance, if they a pose with someone’s hand on their head, i’d draw a similar pose with someone’s hand on their head. it’s not the exact same pose, but they are definitely similar. also they did a fanart of an among us character and i got inspired to do one as well, just of a different colour. i don’t do it often buttt idk if i should crédit them since they inspired it or if i should just leave it?? or even take it down idk?? maybe i’m just too paranoid...
