The map now:
A few comments. First, this is still roughing. The browns are general indicators of contour, not precise yet. The labeled climate zones are rough approximations - while I'm reasonably happy with what's where I suspect I'll move boundaries a bit. (It helps that climate zone boundaries are naturally fuzzy, of course.)
The three unlabeled zones are mountainous terrain; I think it obvious but have learned not to assume too much. The western arc is older and will be rounder-topped (think Appalachian mountain range in the US). The eastern range is newer, taller, sharper - except for where the hammer of the gods crunched it a bit.
Next rough will be river placement. Possibly it will also have national borders roughly noted as well. I figure I'm within a few days of making up my mind what style I'll use for now.
