I'm going to want to make this nicer later, but for drafting purposes, just grabbed some pencil crayons and blocked in the various biomes, as well as adding a couple more to fill in the gaps.
1) (My first addition) Is a huge northern forest, shading from a fairly hot rainforest at the very east coast to a much more seasonal, temperate mixed forest in the west. Two notable features here. First, giant flightless "kicker birds", which... Imagine that a lovely purple chocobo had babies with a rabid, hateful ostrich. They'll potentially be very useful to someone, but they are filled with malice. Second, down at the border with (3), those mountains? Just completely chock-full of jade.
2) Is the ice wastes, with the giant frozen birds (possibly a larger flying relative of the kickers in the forest? Dunno.)
3) Is the scrubland of the interesting (and sometimes wandering) stones!
4) Is forests extending up from the inner sea there. These are riddled with caves, many flooded, and groan with winter ice.
5) The mushroom scrubland! Notably, the weird little border I put on that is to mark "Elevation change", just so that biome border makes sense; I imagine the mushroom scrub as a plateau with a high western edge, tilting down toward the sea in the east.
6, 7, 8) Is all grassland, but not all the same........
6) (my other addition) is overall quite cool, getting none of the warm wind, nor any of the underground heat the rest of the southern grasslands benefit from. Like (7) and (8), there are large grazers here, and like (8) they are hunted by large cats, though the cats here get enormously furry in the cold seasons. There are outcroppings of quartz in the northern areas.
7) Benefits from both the warm winds and presumably some of the geothermal activity so evident in the south; the winters here are largely just dry, not snowy. This climate is ideal for the snakes that infest the area, which drive off a lot of other wildlife, excepting the shaggy beasts, which grow huge here (because they live longer? Because they're a wildly different species?).
8) Is more temperate, benefiting from geothermal heat (and suffering earthquakes and likely other... Events); bovines, wild cats.
9) Is the desert with the huge huge lizards; I'm going to suggest that with the elevation change I threw in to (5), it's likely partly a desert because it's in the rain shadow of that plateau edge. Also, hey, does this share poisonous snakes with the bitey part of the grasslands?
10) Is the foggy boglands; it's down below the plateau edge of (5); very much isolated, this. It kind of feels this might be a chunk that broke off the (5) plateau, maybe?
....
So, look at where your biomes are, their neighbors, and so on; is there anything you want to add to your biomes given this map, or any crossover you want to check in on with the other biomes?
(For myself, I'm like, I feel like all the shaggy herbivores in 6,7,8 should be related, like, could these be Aurochs of different varieties? Maybe with, like, more horns, just because that's a fun look.)
