I'm going to see if I'm understanding you correctly, you want us to figure out how the...geographical plane of the country look, right?
If so, then we may have hot springs at the snow. Yes, I know. You may start thinking of anime and japan, but cold snow and HOT water. That doesn't make sense, but people naturally accepts it. Of course, we can say there are no volcanoes, which I'm sure is the main reason why hot springs exist in a snowy terrain.
Not only that, but I think that we should get to making boundary lines for the races we have so far. They can be foggy, but we already have a good idea on where some of them can fit in. For example, if you look at the map, there is a mountainous area in the middle of the country. Since the gnomes are the suppliers of raw material, they should be the ones who inhabit that area and may just have majority of the territory in the country. Not only that, but, since some of us already said that some races may not like each other, the dwarves boundary for their kingdom can actually be what separate the races and keep them from clawing at each other's throat.
Do you agree?

Now you see, in the middle is a giant plot of land on a country that looks like pieces were just put together. Now, of course, the dwarves won't
definitely own all of that land. I'm thinking where it is near the center before it begins turning into plains near the coasts that the progress of dwarven land stops. You know, before they get to the water.. I believe that that would make sense, since dwarves are more ground than water types. Not only that, but it would also allow races to move around to the other side of the country without
having to cross rocky and dwarven terrain.
Near the bottom of the map is a piece of land, this being marked by an active volcano, could be where the Orcs reside. I say this, because of the fact that the area is relatively small(I'm guessing the smallest area in sq. miles) and therefore not house as many of those dastardly brutes. Not only this, but orcs are already seen as creatures that can survive harsh terrain, conditions, and whatnot because of their shear strength and endurance which is why I set them up near the volcano.
Not only this, but also the position on which they find themselves in. They're at what can be considered the base of the mountain area off to the southwest. Now, they, by their nature, would go off to storm and attack the dwarves for their land, as I couldn't really see the two getting along that well, and if they do, it may just be an agreement for a "cease fire".
