I did Hullen first, for no particular reason. I haven't polished it yet, ofc, but what do you think of the general shape and geography?
Also, expanded on your description a bit :)
"Hullen is the largest of the 3 continents, set to the north of Lella and to the northeast of Syrro. The land is vibrant and full of life, sporting thick rainforests atop high cliffs, sheltering wide valleys with rolling hills and dense woods, all teeming with life. Rivers, lakes and waterfalls, both above and below ground, provide for a gorgeous backdrop and ensure fresh water is never in short supply. Low, cool, misty swamps at either end of the continent harbor all manner of organisms, from toads the size of a head to larger, undocumented creatures that move about just out of the vision of the land's human inhabitants. These swamps are centers of superstition and fear to this day, and because the shape of the land is continually changing, will most likely never be fully mapped.
The Hullen ((for convenience's sake, just referring to the residents plural as the same name)) have traditionally always relied on hunting and gathering for their sustenance, rather than farming and agriculture. Though their soil is rich and easily tilled, Hullen's land has a tendency to overgrow crops quickly if farms are not carefully tended. Hundreds of years ago, the Hullen were primarily wandering tribes, deeply rooted in tradition and giving prayer to the land upon which they lived for it's abundance.
Today, farming has become commonplace near the edges of the continent, away from the aggressive jungles. The capital of the land is situated near the center of the continent, sheltered on all sides by jungle covered cliffs."
If you like it, I'd enjoy doing the other 2 continents, as this didn't take too long to do, only an hour or 2. I'd also finish this picture up, probably mess with the colors and throw a filter on, make it clear where the capital is, maybe add more locations as they start to come up. If you don't be honest about it, at least, you won't hurt my feelings and I'd rather not spend more time on something that won't be used :)
