I chose to do Captain Rex because he is my

favorite Star Wars character and when he ran into the outpost guns blazing I was thinking "Will this  super cool trooper survive" then he snapped the droids neck

I knew he was my favorite character. So in tribute I chose to do a white silhouette to represent the batch of troopers known as Echo squad, who Rex called a batch of shinies

or in experienced clones (who all died besides echo) and a light blue for the kaminoian s

sky and a remembrance of all Rex's lost Brothers. I would not change a thing.
