I like the general feel of the map, but I have a few points beyond what I think have been talked about so far.
I think it would be nice if the the elevations had a bit more weight to them somehow, perhaps by affecting a shadow cast along a line so that the heights were more clear. Currently the height illustration is adequate, but tends to get lost in the "greening" occassionally and doesn'tseem to leap out as much as it would seem possible.
I'd drop the white outline for the land masses in favor of another color now that I'd decided to go with a similar color for the lakes and rivers. That's a personal thing perhaps, but I think that a darker color would still provide contrast without washing things out. Of course, since you've indicated that this is for print the actual whiteness will probably be much more subdued so it becomes a print issue as well.
I think the greening effect looks awful, especially as the map moves away from the left. The more dramatic the green, the less appropriate it looks and the more it looks like nuclear moss. If the effect is supposed to show forests, meadows, and not moss I think a more subdued green would be nicer. Perhaps a collection of greens, browns and yellows. If the map isn't supposed to show a completely bald rock of a continent I think I'd add in some greens throughout the entire map (properly translucent, because your initial continent work is quite nice), and maybe scrub the forests and such on with a texturing effect of some sort perhaps.
BTW, is that your own border creation? It's quite nice. Keep up the good work!
