Did you see what Waldronate meant about odd rivers? For all the awesomeness of the mountains generated this way, to me it's jarring to have rivers going nowhere. Or for that matter, ending improbably. Your Sevauvud/ Aelon/ Geran one, and the Ponzala/ Cirelia ones probably ought to behave differently, winding up at the ocean. If I generate some reasonably plausible terrain with Fractal Terrains, I still manually complete "stuck" rivers, connect mid-continent dead-end lakes with an outflow somehow, and otherwise fix stuff that just looks unlikely. I mean, yeah, there are real-world basins with no outflow - but most minor ones either fill up until they do overflow, or (ages later) have worn that outflow down to a slot through the 'barrier rim'. Here I'm referring to your southern Kaelia and northwestern Sevauvud terminal lakes. The big one mid-Elohabor could be plausible. You could sell me on the one in western Elohabor having no outlet - depends on the exact terrain south of it and how much rainfall the basin gets.
As far as the biomes / climate you're depicting - they're not inherently implausible, just don't fall into a stereotypical "north = snowy wastes, south = arid desert" without planning to do so. The latitudes you're working with make all the difference. Deserts, on an Earthlike world, would tend to fall around the 20-35 degree north and south range; a matter of air circulation, not "equator=hot". Other wetness and dryness come both from latitude and generalized seasonal airflow, coupled with rain-shadow effects from mountain chains. Ice could just as well be antarctic as arctic. Just how much of your globe does this map depict, and where on the globe is it? <never mind - I see the later post placing this on your globe.>
<I'd suggest calling the north edge just 70 or 80 degrees north, which may be what you mean by "near the north pole", since there's none of the distortion you'd expect on a rectangular projection as it nears 90 degrees north. But yeah, if you figure the south edge as a sahara-ish latitude, drier climate is quite believable.>
They're nice maps, both the political and the topographic versions. Personally, I want the canal concession at the south of Kaelia. The little terminal lake there is actually ideal to supply water to the 'peak' of a set of locks going over the divide.
