something's off just around your equator, I think... but I can't figure out what, it just feels off... it should be *hotter* on the land about the equator... not cooler... right? Maybe it's something easily fixed when adding in precipitation?
I've been using a different method, so I'm not sure :/
Also... The lines/transitions seem too smooth somehow ... (worse to the edges of the map, in any direction, so might be details you've not added yet?)
I wish I could be more help, but I'm new to this and don't want to say something wrong when it's not cause I did mine different methods!
