Kronos (reborn) topographic

[Harrg]

I`m working on the Ice Age relief of the north.
This is hard, because I need imagine how ice shields moved and how it influenced on rivers and etc. Also I try imagine how rivers change them streames, previouse than stay on the modern positions.
Lands on the north of the huge middle orogeny looks flat and congenerical. I whant add here some ancient basins(punctir line). Today it is a flood plains with some lakes.
I also revise the relative heights by lowering the altitude in the southern part of the continent
I try to pay special attention to the large river in the center of the continent. I am planning to add a large delta here.
I have not decided yet and have no idea how the river will look like. I think the best candidate would be a mix of Amazon and Ganges
I try to lower the relief here to emphasize the sinking of the southern plate under the northern.
I feel that in the southern part of the continent some rivers need to be redirected into indoor pools. Because now, they are all oriented towards one of the coasts


I hope for feedback.
Thanks
