Did you post it for any impromptu map testing?
Join the official group
http://steamcommunity.com/groups/TF2Mappers
Go to the group chat
type in: "!add <map name> <download url>"
example: !add cp_fishfood_a2
https://tf2maps.net/downloads/fishfood.2475/download?version=5210
It should get automatically added to the list for testing
There would be an announcement that pops up whenever an admin or vip decides to start a test (you can also scour the group chat to see if there's one starting sometime) if you want to join in.
Otherwise you can check
https://feedback.tf2maps.net/ and click on your map name to see any feedback people leave. You can also download the map demo, and watch it.
