I really like this. I would never argue with HR on maps. I don't like looking stupid.

For a "serious" modern map, I would definitely damp out the shadows and highlights a bit. Probably reduce saturations some too.

As it is, while perhaps less scientific in nature, it is strongly evocative. It gives a feel of the landscape. It makes me see the place, and I see a lot of exciting nooks for adventure.

You realize, of course, a tutorial is now required.
