Request for a Patchwork Droid : MP-13 an Astro/Power Droid. [Asok]

I've made a request on these forums before and was overjoyed to see it come about.

I hope today I present you with a character that someone once again finds interesting enough to depict with another wondrous piece of artwork.

Name: MP-13

The Story:
MP is a patchwork droid that started as a Maintenance Power Droid, which later got mostly destroyed in a firefight between Corsec and Imperial Remnant Troops.

He survived but was scavenged by a group of Ugnaughts who simply tore out anything not important - installed some strange power source they couldn't figure out and welded him back together.

He later escaped by sneaking onto a freighter bound for Tatooine.

On Tatooine he found himself outside the home of a group of rogue Selonians, and soon came to notice that one of them, a lone female, was a tinkerer or sorts. He attempted to request assistance but was repeatedly turned away.
After finally convincing her to help him, the two realized that the necessary parts were too expensive, so MP simply stole an R5 astromech to use for parts.

The resulting concoction is truly a frankendroid.

Appearance:
He has a malformed body made out of the power droid shell but with astromech maintenance hatches.
He has the legs to either side of the R5, but they face backwards like in older astromech models.
And instead of a third tread he has an archaic wheel.
He has the shaped dome of the R5 as well but replaced numerous sensors.
His vocabulator is reconstructed from both droids so he whistles and beeps like your standard Astromech, but it's often interrupted by a loud and grating "GONK".
Loose wires can be seen in numerous places with no idea as to importance.

As to his coloration, he doesn't officially have one yet. Of note I would think he would be rusted in a few places and my favorite color is teal. *shrugs*

I adore playing this character - hes usually the comic relief of our RP group for Star Wars the RPG.
He repeatedly gets into trouble - be it almost stolen, almost destroyed, or who knows what.

To anyone who takes up this character challenge, I thank you from the bottom of my heart.

If there is any information you all think I left out, please let me know.
I could possibly even attempt a simple sketch if you like.
