Looks OK. I suggest wearing the headstrap, and getting that comfortable, then adding the quest in (may need to play with the angle of the arms).
Tray having the battery facing the other way if the cable will reach, so the cable comes across the top of the headset. My cable length is much better this way (loop it through the velcro at the back).
I've found having the vertical strap going from the headset to the battery pack (assisted with some velcro loops from the velcro supplied), helps the counterweight offset a bit more, but it's not essential, and having it on the forehead band may be more comfortable overall (not tried it).
Key for me was finding the point at which the weight is on the headstrap, and not the facial interface, but still having the facial interface as close as possible..
Doesn't look like you've added any foam to the back or the horizontal straps yet, that might help comfort too.
