I like it, I think it's good. The choice of salmon-ey pink land colour seems fairly unique but I actually really like that. On the other hand, I don't think the colour of the ocean goes well with it, perhaps a less saturated blue. Also I'm not fond of the water texture itself, I think maybe it'd look better if it wasn't so dominant.
A border to frame the entire map might be worth considering. Always adds a nice bit of finish. And of course you can add a compass rose and scale markers, etc etc. Little things, all personal preference! (If I recall correctly, there are some nice compass rose brushes/shapes in the mapping elements board somewhere.)
