Quite a nice map to start with.
A good choice of colours... very subtle, even a little too much. Perhaps you could go for just a little more saturation.
Nice variant coastlines, but overall, your island/continent suffers from the "I have to fit the page" syndrom. Try to avoid stretches of coastline parallel to the page's edges.
You should put a little more effort into the mountains. As it is now, most of them look like a single giant slug of a hill, without any variation. Try to add more ridges, like in the mountains south of Primo Sole.
You might also want to consider adding some rivers. In the style you use here, rivers in the blue colour of your coastline would fit in perfectly.
I hope I wasn't too harsh... you could have done a loooooot worse.
