I thought this was resolved due to the very good explanation from @grod but I as a moderator will just state this again so we got this issue out of the way once and for all: this pattern is different enough! It uses the same elements (hills, cactus and sun) but the individual elements are arranged in different ways which makes it a different pattern. 😄 @Maggieeee
@knotedbyme and @Maggieeee it is similar, but the mountains/ dunes are different and the cactus placement is different so that probably why it was accepted (:
