Attachment 49613
I've highlighted the problematic parts of your rivers.
Green for divergence, cyan for places where the rivers don't appear to be flowing downhill unless you have some very strange terrain that isn't being indicated, yellow for deltas that are too big for the river systems feeding them, and red for a river/lake system starting very close to an endorheic lake. The east lake requires lots of rainfall to form, while the west lake requires an extremely arid climate to avoid overflowing and having an outlet.
