Here's my entry for the Rebels customizing contest. I have no idea what type of characters we'll see, but it looks like we'll get grittier characters, fewer Force users, etc. So, I've decided to create a mechanic. He's a Cerean mechanic, slightly elderly, used to work for a Separatist engineering unit until the war ended. He now just picks up odd jobs where he can.
I've always liked the Cerean race. There's something that looks inherently wise in their faces. I decided to make this guy look like he didn't have a set uniform, something resembling mechanics overalls. I also gave him a do-rag to clean up all the grease he deals with.
