I don't see anything wrong with the texturing. (then again maybe Im biased)
You might want to check in the upper left corner, looks like a stray bit got hit with your coastal outline and chopped off
The rivers don't look to bad mostly, maybe a bit straight in a few places. You may want to attend to the one in Salim's tears before the river police see it. There's one or 2 other rivers with some concerns, unless you have a good reasoning for them.
You could perhaps work with an inverted bevel to give them a bit of depth perhaps, but overall it's pretty nice.
