I was looking for a way to cover up the ugly gray motor covering in my subways. Doing a search on the forum I found a few examples from Alex M and Sirt. Two guys I have never met but they took the time to make a post of what they did. Reading their techniques and adding some of my own I was able to cover that grey motor.
1. Found a decent interior picture of a subway car online.
2. Found more pictures of people especially people facing backwards to make it look like they are next to the window facing forward. Also added a few more pictures to add some comic relief. Notice Dexter Morgan and Walt from Breaking Bad. Using Photoshop I was able to add these new photos to make a whole new scene.
3. Cut out the photos and glued them to the gray cover.
4. Put top back on and tested.
