Its pretty good and theres a few points we can make better but its a good start so thumbs up !

What I would recommend is to put your terrain down and sort out the mountains and then think about the rivers. You have water traveling towards the mountains and then down the stepped valley. So its not far out but that would be a little odd.

I think some shading on one side of the mountains would help bring them out so that you dont need so bold a line to show the peaks. Thats not too hard to do so you will get the hang of that in no time. Need to get a bit familiar with layer effects like multiplying shading in on a layer.

Cool. We'll see some more maps and they will improve as you do each one.
