A lot of whether something makes sense will come with more details than are presented here. The rivers don't seem to have any major issues, but they still could in a different manner than just the basic rules. Except one basic rule... rivers rarely if ever hit at 90 degree angles, in nature, but this being a rough, I will just mention that in passing. How big is this continent? At what latitude and longitude is it sitting?

Even sitting north or south of the equator may alter its reality by where cold and warm currents sit...

Tectonics, no I'm not an expert, but, tectonically speaking, I see some possible issues with what forces would cause the pattern of mountains here. Basic mountain structure puts one side steep, the other into rolling hills. So, you've got issues here.

What is with the cliffs and plateau regions? Not typically what I would call major land formations on a continental scale.
