This map looks so beautiful, honey! ^^
Though for future reference, all maps must be 513x513, the size of 512x512 is for presets. You can also use the size 1025x1025, that also works on FeralHeart.
Plus you can add more detail to your height map!
I also think you should Modify your first post with this new map link so users can find it more quickly! Maybe upload images of your map to imgur then right click the image and select "copy link location". Then paste the link provided in between the code here:
[img]IMAGE LINK HERE[/img]
