An extremely general observation would be that, assuming this is a equiractangular projection, your polar land masses will be visually stretched by the projection, which doesn't seem to happening here. It might also be more useful to label latitude zones as tropical, subtropical, temperate and polar as very simplified climate zones. The world also seems to have most of its habitable land surface in the tropical to subtropical zones. Another general question would be the size of the planet in question.

After those general observations, we head to the continent where you have some serious river issues, with two that seem to go from sea to sea. Also there is a river that hooks around some hills after heading for one ocean, suggesting a downward terrain which then hooks all the way back to another body of water, suggesting a pretty major shift in terrain that would require some explanation we aren't seeing in the map. And even appears a bit counterintuitive when compared to the height indicators we're provided.

Such a land sparse world would have (potentially) very simple ocean currents with the arctic zones being very isolated from warmer currents, not sure of all the implications so many straight currents might have.

That's at least a few considerations for a start.
