Hi, this is a good seed, Haven't got mucb time, but here it is:
Besides, 4 biomes in just 1500 blocks.
Endportal right at the big watermountain.
What version of Minecraft are you using and what are the coordinates of the portal room?
I used PCMCv1.7.10 to create a world with the seed "3865090143002749767" and spawned in a desert.
(PCMCv1.9 or later will have the strongholds and end portals even farther away from spawn)
Here's the map.

If you have questions about the maps I post as attachments or Amidst and the like read this thread:
