Hey Chris, where are the castles? I see none...
Joke aside, i like the shape of the landmass, especially the part above the imaginary equator. Now to the looks of it: there are two striking points imo. First, everything is too dark. There is barely any spot with seem to have natural/soft colours. Might be ok if your setup was a devastaded/scorched/perpetual twilight world; to me, its a bit too dark to be fun
Secondly, and related, its what Ascension said. There is roughness all over the place, barely a level spot; it looks quite uninhabitable at this point, imo. I mean, even the shores seem to be replaced by cliffs
A newly born volcanic island might look like that i think... On the bright side, the bumpiness for the terrain looks pretty good, and theres a lot of ranges, crevices, peaks that u can use as landmarks, and by toning down some of the land around those, u can get a pretty belivable terrain. You can also try to alternate small size/high detail/roughness areas with greater size/less features ones, as it makes things varied and natural.
Also (but thats just me), the continent stretching outside the map (N and S), prevents the possibility of circumnavigating the landmass, which i always like to be able to do
That points aside, nice first map! Keep posting updates pls, im in the same boast as u are, and i'd love some reciprocal feedback
