A good place to compare is Google maps. Zoom in to the same approximate scale and look at what features are visible.

I think this scale is close to yours:

Note that you can't really see any of the rivers. Even the Nile is only visible because of the vegetation growing along it.

If I didn't zoom in enough to match your scale, go ahead and do so and note what is actually visible at the scale you end up at.
