Nikto mechanic/pilot and his pushy droid companion [Asok]

So this is a character I've had around since around 2004-ish, yet it's never occurred to me to request a drawing of him on these forums. But anyway.. here we go.

Chilko Tosh is a Kajain'sa'Nikto, whose parents were originally naturalists stationed on a distant planet in the last days of the Old Republic. After their premature deaths, Chilko left as an early teenager to make his own way in the galaxy. By the time the Empire came to power, he had found himself flying deliveries for a mechanic's shop on Malastare. Although he was naturally comfortable behind the controls of his delivery speeder, his real talent became obvious when he began tinkering with droids at the mechanic shop. Impressed, his boss gave him a job repairing old droids, where he eventually became acquainted with an orange-paneled R-5 unit that would eventually become his best friend. Known simply as "R", the ornery little droid accompanied Chilko when he left to join the Rebel Alliance as a pilot shortly before the Battle of Yavin. With his little mechanical partner, he now flies Y-wings in a ragtag squadron, but he's still most at home repairing droids and tinkering with his ship.

Wow, that bio was a bit long. Anyway, here's a bit about his personality/appearance:

He's taller than average, and pretty gangly, but other than that, he just looks like your average Nikto. Introverted by nature since his parents died, Chilko's way more comfortable around machines than other sentients. Social graces don't come naturally to him, so he's a bit of an oddball in his squadron. As a result, he spends much of his free time in the flight bay, making little repairs on his Y-wing and volunteering with droid repair. His R-5 astromech is always with him, and is the polar opposite of the quiet Nikto. Loud, abrasive, and pushy, the little droid more often than not is the one that speaks up for Chilko when the former is too reserved.

As for the picture, I'd ideally like to see the two of them having quiet moment with Chilko doing some minor repairs to either R or some generic little piece of machinery. Pose and whatever is up to the artist, as is clothing, but I kinda pictured him in his flightsuit, kinda rolled down with an undershirt on while he works on his stuff, but whatever. I'm not terribly picky about it.

Many thanks to whoever takes this! I have never been let down by you guys and I don't intend to start now.
