Anaru never wanted the responsibility of being a Toa, he much preferred alone time exploring and honing his arts over his Matoran duties. When destiny called, he was less than thrilled.
Instead of apprehending the dark hunter that killed his Toa-brother, he took grim murderous revenge, then set off on his own into self imposed exile. Nobody argued that point though. He wanders, does his best to help any he meets, and takes justice into his own hands when honor and the Toa way fail.
Hey again, Anaru. lol. Guess this was what you were talking about when you said "plain black Miru". I'm liking this version, but the thing is, I'm not the average MOCcer and think this guy should be what a Titan-sized Mata set should be. And I think that's what you're going for, what with the Mata-esque fingers and all. So I'll advise you like you're going for that. I actually liked the random pins sticking out on his shins, so I might advise bringing them back. Just for some extra texture on otherwise nice but plainish legs. The gears make him unique- love those. Needs more purple, especially on the legs. Maybe above the knees from how you say the purple is flesh. And that's all I can think of. Liking his weapon, but it seemed a bit sleeker in the last version.
Oh- and nice job with the eyes. As for the Miru. . . We'll wait on it :D
