Quite good looking map for your first one. Nice layout, vibrant colours. I really like the way you did your coastal waters.
Your rivers are problematic though. It is quite difficult to follow them, due to their colour, but it seems you have quite a lot of river infractions here.... rivers that cross mountains, split as they go downstreams or even cross the continent. You also weren't to precise with drawing them... sometimes convergent rivers don't meet correctly.
In my view the style of your settlements make the map look a little .... measly. Perhaps changing the disc-shapes to unfilled circles would work better.
For consistency's sake you should also continue the black-and-white checkered border at the sides.
And while I am looking at the border... is that part of the parchment or did you draw it yourself? It's gorgeous!
