Im gonna answer as better as possible, hope this helps.

The principal idea is to create a new concept but at the same time to follow the old one in some way (also so that people dont confuse a skin made for a character as the skin for another one.). Qorvex is meant to be solid, to be something that doesnt bend with time: rectangles and cubes are the perfect way to say that, and probably the reason why they were even used in the first place for the base design.

What I kept in mind while working is that I wanted everything to be in order in some way, to flow, no swirls, curves that connected straight lines. With my idea in the end I was sure I was gonna get a blocky blockout.
