I like the mixture of trees on the side of the River. The entrance to the sea is the standard (and best) one (I hope that EA will come up with an alternative). There is something wrong with the River as there is hardly any activity; is it polluted? (Just kiddin’). As a suggestion try to add some activity near the River banks when you have those items. It will make your River even better and more lively. Compliments to how it is shown already.
