@Dakib it seems like @1111233 and alekc_a25 on Instagram used the same reference: artwork by cartoon_cookie on Instagram. @1111233 credits this artist in her bio.
The artwork by cartoon_cookie was posted in June 2019. @1111233 and alekc_a25 on Instagram seem to have independently used this as references for their patterns. That's why colour scheme and composition are very similar. But if you look at the size of the patterns (@1111233's patterns have sizes around 30x100 and alekc_a25 patterns have the size 40x128) and the details, there are clear differences.
