I like the custom torso, but the legs are too short. You need custom legs, because you'll never be able to get the right length with the inika build. I actually like the really broad shoulders, I think it adds character to the moc. I have a critique for the color scheme though. I think it lacks color, and looks a but monotone, but that could easily be fixed by maybe just adding some trans blue (or maybe trans purple) parts in there, just make sure they are consistent with each other.
For a name, you want to find a word that fits his character really well, translate it into either latin or greek, and then make some small tweaks to the word to make it sound catchy. Generally, if it's a male you want a name ending in 'o' or 'um' (there are exceptions) and for females you want something ending in 'a' or 'i' (again, there are exceptions).
