The "trick" with the map is that Seira is supposed to be 1950s science fiction Venus, complete with swamp-dwelling "dinosaurs" based on outdated ideas of dinosaurs a slumbering swamp-dwelling reptiles (pic related), so I just used an actual map of Venus (the map was only for one hemisphere, so I had to rotate and stretch it to match the proportions of a standard Mercator projection world map, and add some land in the corners where the continents would "roll over" to the other side). So all the elevations are actually based on real elevations, I just chose the midway point to be sea level. Granted, given how different Earth's and Venus' tectonics are, it doesn't really translate exactly to a terrestrial planet.
All the land being relatively low is intentional, though, since the idea is that Seira is an Earth-sized planet but considerably warmer, so there's no glaciers and much of what on Earth would be coastal regions and lowland is instead shallow sea. I probably should have made the oceans deeper, though, since currently a lot of it is much less than the average depth of ocean on Earth. Or just edit the map so the numbers are <4 km and 4+ km (4 km being the average ocean depth outside continental shelves on Earth).

One of the most prominent groups of Seiran pseudoamphibians are the palussaurids, a group of midsized to extremely large amphibious carnivores. The smaller species include intelligent pack-hunters that are often kept as pets by the Seirans (like humans keep dogs) and various aquatic or amphibious fish-eaters, while the largest are massive apex predators that are effectively like a cross between giant crocodiles and theropod dinosaurs.
