Describe what you mean by techwear and real pockets - I have yet to find a short that you describe that DOES have real pockets. But trye Nike and uniqlo - I have a pair of short-inseam cargo shorts I got there last year.
Rad, dude. I think it's cool how wholeheartedly you've embraced this.
Random thought, but a year or two ago @spacepope and I decided at the last minute to see Dir En Grey live (really, it was because @brad-t told me it would "change my life" - and it did), but they were wearing almost entirely rick and julius. It was awesome, and totally added to the show. By contrast, when I went and saw The Sword a few months ago (one of my favorite bands), they were mostly in gym...
That looks really nice (color is great), but I don't know why you're buttoning it that way. Try buttoning the middle 2/3 buttons instead, and leave the lower ones undone (here's a link to show what I mean: http://dieworkwear.com/post/14514798204/valstar-and-ring-jackets-blousons). Hard to tell if there's anything "troubling" about the fit in the pictures you've shown (as the armholes don't look particularly low in either photo), but it's more about the way the piece feels.
I turn up the sleeves on mine a lot. Sometimes pull them up to my forearms. Works with the vibe/material just fine. And it's also not fitted - I can easily wear a mid-weight sweater underneath. One of the easiest-to-wear pieces of clothing I have in my closet.
