Absent minded Rodian technician [Asok]

This is my first request, so here it goes. I have an NPC in the RPG I'm running named Sloop. He's one of those characters that I include in some way, shape, or form and he's always a Rodian. Anyways, in his current rendition he's the ship's technician for the mercenary group the players are in. Here's the description I gave the players of him... Before you stands a twig of a Rodian. His skin is a darker blue with a purplish tint. He wears a grey jumpsuit that he uses only as a pair of pants, with the upper half of it bunched up and tied around his waist. On his upper body he has a tight shirt with a vest worn over it. The vest has a multitude of pockets, clamps, and such for all of the tools he uses as the ship's mechanic. Instead of the typical mohawk frills Rodians have, his frills are around the sides of his face and chin; giving him an 'unshaven' appearance if he were human.
Personality: Sloop is a troublemaker(the players had to break him out of the local jail the first time they met him). He's constantly getting into some sort of predicament the players have to get him out of. He'll pick fights in the bar or work up gambling debts. He's always gambling when he knows he doesn't have the credits to pay up. Sloop's a technical genius but doesn't have much common sense, which is probably why he causes trouble and works up his gambling debts. He feels at home in any kind of engine bay or workshop. He gets nervous when he's away from a ship and out in the wilderness. I cases like this he's usually seen fiddling with some piece of tech, such as his blaster pistol, datapad, or comlink; anything technical that he can take apart and put back together.

Wow, didn't mean to write that much. Please do what you can with Sloop, I'm up for pretty much any re-working the artist wants to do with him. The one thing I really want for his appearance is the way his frills look)on the sides of his face and under his chin). Other than that do what you want, thanks :)
