Thanks for your advice guys I just updated the river style and added some hills and fields. The southern part of the continent actually is higher than the north so I think the long river is now behaving more logically. The southern coast consists mostly of rocky scarps and steep bluffs. Are there any typical geographical features that higher ground usually has? Should I add more hills or mountains to the south? Furthermore, does the higher altitude usually affect the climate significantlly?
