I like the blue you chose, and I do think some of the icons are stronger than what Steam originally had.
However, I wouldn’t really call your version an update.
It’s lacking finesse. The icons, imagery, and text are too crowded, and most of the elements are too large. I also don’t think things are that well organized. Design doesn’t just mean “looks”, it also means “how it works”, and I think you didn’t overhaul or help the “how it works” part in your redesign. The badge numbers on the top nav icons are way too small, and the nav icons are too large.
Also, your time and date information / top nav icons are all “kissing” the edges of the artboard, which is really not attractive.
