Can someone help me find a seed like this for my forever world?

Ignore the fire netherack thing, idk why I put that nether grass up top but just make sure there’s a stronghold in that area, please note the lily pad up top as a swamp, the ice and prismarine walls are ice spikes, if you can, try to have some structures in there, like a mansion and a prismarine temple (idk if I got the names right but you know what I mean) I’m surprised people can actually find stuff like this lol
