I started on a TR revision today here are the steps before I got to tired and decided to hit the bed

First Image: basic shapes, I am not the best at this but I try, TR is all about curves and circles

Third Image: Add some circles and a little bit of styling also add the text overlay so I can size up where the windows need to go
