This is much better! Good job
I liked the edits you have made. Now a couple of more points - including one very important!
1). I just realised that lake Tharthar (the big lake at the top left) is on the wrong side of the Tigris river! To be more exact, the lake is in the right place, but the Tigris river (incorrectly) flows to the east of the lake, whereas in reality it should flow directly west from Baghdad, skirting the west side of the lake!
This is quite a big mistake and never noticed it before! if you could redirect the river so that it goes to the left of the lake, instead of the right, that would be useful!
2). Also, the area around lake Tharthar is known for the ziziphus trees that grow around it, and it is a major source of irrigation water for farming. It would be good to add some trees on that area.
Good work MWY, we are making great progress!
