Just a passing comment :
For all the rejection I have of the lines on costumes that I associate with the MCU style, I find that this rendering removing the Captain America/Starlord uniform look makes the costume feel like something out of a Jack Kirby comic book.
I mean, based on this image, I can imagine another real-life view of this costume that might still not be the “classic Superman suit”, but whose visual direction would certainly, and ironically, have piqued my curiosity...
Ideally, I'd have liked something like the Fleisher suit, and I have to say that, at times, it seems to me that this new costume might have a little retro SF feel to it, which is a vibe I usually like very much.
In any case, what I'm guessing from the belt looks pretty vintage to me.
We'll see... I'm eager to see some set pics to get a better idea of the mood Gunn is going for. I know it's different for everyone, but personally, the artistic direction weighs a lot in my interest in this film.
