Ok Tempest's lines are essentially done (tho I do need to add more stuff for info and whatnot, but at least the overall design is down). The left line set will be shrunk down later, but that's basically his "clean" lines, when he was first built.
The right one is several years later, after he's had some adventures and such, so he's more beat up, damaged, and had some other additions, like a scarf (cuz dramatic), a cockpit in his chest (that he didn't ask for lol), metal spikes he uses as makeshift railgun bullets (he figured out how to use his tail as a makeshift railgun), plus some storage compartments, the ones on his hips are his own personal ones, but the one on his outer right leg is for the bike, and the smaller one on the outer left leg is for his pilot, Kim Ryder, to use.
He also has several sensors and cameras throughout his body, such as on his knees, elbows, top of arms, shoulders, tail, and on the crest on his head. The "eyes" that you see are false, and he does not actually perceive anything thru them. They are just there for social interactions essentially, to give someone else a focus spot when talking to him, as well as help him show his own emotions and such.
Anyways, I have way more notes and such, so the finished pic will have a lot to read.
