Faux Tin Ceiling Tiles

We have a room on our first floor that has needed a remodel since we moved here some 20 years ago. Actually our home has many rooms that need help from a remodel.  We do what we can do ourselves mostly.
I have loved the look of tin ceilings for many years and wanted to add one in our home.  The task seemed not only difficult and expensive but had drawbacks with the installation process because we would have to put up plywood so we could nail the tin tiles into it.  That would lower our ceilings and in some cases if the plaster gave way from the lathe, it might not support the weight.  So I had given up on real tin tiles and was looking at faux tin ceiling tiles.  I found some YouTube videos from decorativeceilingtiles.net.  They were light weight PVC tiles that were glued up on the ceiling.  I thought they were a good fit for us.  I ordered the antique gold Gothic Reims 2 foot square ceiling tiles.  They arrived in about 2 weeks.  They were out of stock on the Instant Grab glue when I ordered the tiles.  But I found it on Amazon for about half the price per tube.  It came in a full case of 24 tubes.  The estimator on the tile web site said we would need about 7-9 tubes.  Turns out we used 16 tubes to put up the ceiling tiles and the cornice pieces so I was glad we ordered the case from Amazon.
With the help of my son and daughter, we put up the ceiling tiles in about 4 1/2 hours.  I ordered the cornice you see in the pictures about a week later and it took us about 2 hours to put it up.  The results are pretty stunning.

The results are just stunning:

We decided to use the same treatment in the closet for this room.  I ordered a few more tiles.  We calculated that we needed 6 tiles.  We had 1 full tile left over from the first order.  The web site's tile estimator is pretty good.
The second order of tiles wanted to crack and chip when we cut them.  We had absolutely no problems with cuts on the first order of tiles.  I used my Fiskars Amplify scissors on both orders.  I thought the second shipment of tiles were possibly old or bad.  I was really concerned that the closet wouldn't get finished but the cut edges are not very noticeable in the closet.  I contacted the supplier and they suggested scoring with a cutter before using scissors to cut the tiles next time.  Perhaps they are right or perhaps it is change in humidity in our home or how they were stored in the warehouse or my scissors were duller or something else.  I don't know but the supplier sent me replacement tiles for no charge and were very nice about it all.  I am very pleased with their customer service.
We are going to use their product in two other rooms of our house and possible the upstairs hallway.  I am trying to decide if it would be okay to change to a different style of ceiling in rooms or if I need to use the same tile and color in each room.
