warcraft 3 undead base

i am creating a halls of the dead from warcraft3 a fun game this will probably take a while longer than the new castle project i have a few images already here they are
i will update this as i go the inside is the problem you never get to see it and the now you do get to see inside of in wow is a black citadel instead i have finished the outside of the undead base but i am incapable of doing the inside until i know what the inside looks like i will as the name says it is a undead base i think i might make a actual undead base with a crypt a graveyard and an abandoned mineshaft no units sadly but if someone wants to make a mod and a mod installer that will let there be a way to make/summon units for Warcraft 3 id be eternally grateful to them untill i die,,,,,,, or forget probably forget in a week i have made some of the essentials except a gold mine which might be the hardest if i don't count a frost wyrm summoning thing i cant remember the name i will make a mine later

Additional Notes

if you have an image of what it looks like on the inside please show me i will appreciate it
