Your rivers are doing non-realistic things like forking downstream with two separate channels going to the sea. Why do so many people not understand how rivers work? Two or more rivers join to form forks, they do not split apart and fork away from each other.

Anamolies exist in the real world, but only at very small scale, they split around islands then rejoin on the otherside, or they form deltas near the mouth of extensive flat regions depositing silt that forms separate channels, but honestly, most rivers do not have a delta, its actually somewhat rare with the Nile, Missippi and Ganges among the examples that exist.

The rest of your map seems sound, but the rivers are screwed up. Please fix and show us an update!
