Grid Map of Island Archipelago I made

I made random map of an island chain. I don’t know what I’m gonna use it for but maybe sometime in the future it’ll be a project of sorts.

What do you think of it, and what are some ideas as to what it could it be used for?

-Made using Paint3D and Google Draw-

I would like to see this with the specific terrain. Nice!

It looks good! But I would map out terrain elevations too to give it more detail.
