The graticule (grid) doesn't make sense for this map.

If it's meant to be a lat-lon graticule, then a square grid means the projection is Plate Carree/Equirectangular, which has some specialized uses, but would make a horrible choice for a continental reference map as it causes severe and quite ugly distortion near the poles. Your map doesn't show this but judging by the scale and the terrain, this map includes high latitudes which should show severe distortion in this projection. That would actually make the land distorted the opposite way.

Think about how the meridians get closer and closer together so that they meet at the poles, and the parallels are circles around the poles that obviously get smaller as they get closer to the poles. To draw them as a rectangular grid obviously means distorting things. (Which isn't to say other projections don't distort things, but it's a matter of picking the projection which avoids distorting the things you care about for the particular map you are making)

A compass rose and scale bar are also inappropriate in the projection and extent implied by this graticule. Plate Carree does not preserve bearings so a compass is wrong (It preserves the cardinal directions, but squashes the "diagonals"), and the high distortion you'd get near the poles means there's no true linear scale either.

For a continent like this, covering some higher latitudes and with greater extent east-west than north-south, a conic projection would make more sense. This still wouldn't preserve bearings, but would potentially keep linear scale close enough to true over the whole area to justify a scale bar.

So I'd suggest ditching the graticule, or replacing it with a conic one. You should also label it if you have one as it really doesn't accomplish much if it isn't labelled.

There are other kinds of graticule for other coordinate systems like UTM or the locator grids used on street maps. I don't think they really make sense for a general reference type map like this.
