Nice work , i will say my opinion about those maps as a noob ZM player from long time and as a server admon.
map#1 : it was the first map removed from hashtag zombies , its very easy for zombies , no spots to hide or defend , i dont remember that humans won one round in that map , no way to replay it for me -1.
map#2 : the map has been suggested from me from long time , Calig added it , but then i found a bug in the map . also the map is too big . some spots are impossible for zombies , for me -1 .
map#3 :this map is good for hunting mod (low hp for zm and easy to kill) but not good for our ZM server . the map has no spots for humans . for me -1 .
map#4 : already have a version of the map which we were playing in eufrag , i dont think there is a need to add new version . for me -1 .
map#5 : i checked it , looks good but easy for zombies . for me +1.
map#6 : very good one. idk how did not i find it before XD . balanced not boring and gg. for me +1.
map#7 : although the map size is 15mb , but its small in game lol . only 2 or 3 spots ., for me -1 .
map#8 : gg very good , for me +1 .
map#9 :nice and cool , but there is one spot which is hard for zombies , i hope the mapper could remove it. for me +1.
map#10 : no spots for humans wtf , also the map has other server ip, so for me -1 .
map#11 : it was in ZMkilerZ , not good , players used to avoid playing it, for me -1.
