Kingdoms of Cassonia and Latan - WIP

[ElderGreen]

Hey all,

Just started working on a new map, depicting another part of the same setting from the Kawyn map I posted in 'Finished Maps' two days ago.
Figured I'd make a WIP thread here to get some feedback as the process is ongoing.

Currently I have coastlines, major lakes and a massive river delta finished. The river delta system is probably what I need most feedback on. Spent some time looking at reference pictures but you can never have enough thoughts and opinions on something like this.

For context, the topography of this central peninsula is for the most part very flat with most parts south of that inland delta being swamp and marsh; the occasional hilltop poking out. For scale, the lake on the central peninsula is about 90km wide east to west at its widest point.
