SQL-Server-2012

This is my database design for a geo electoral information system. In this system

The candidate signs up and creates his profile, then subscribes to a package plan.
The candidate can set up his account his allies/assistant.
Then a candidate selects the target constituency and posts the textual notification, events, videos and much more.
On the other hand voters belong to that constituency are able to search their candidate via Gis system and then follow their candidate and gets their notification, videos and event news.

Please have a look at the diagram and suggest if I had made some mistake or if more modification can be done for the improvement.

This is perfect database design,But below are the few suggestion to make the database architecture more reliable

1) Add "DistId" in tblCity table and create reference key between TblCity and TblDistrict
2) Remove "City" column from TblAppUserDetails and add "CityId"
3) Create reference between TblCity and TblAppUserDetails
4) Repeat STEP 2,3 for all the tables which have "City" column

Hope this helps
