Hi Nicholas,
I like the idea and material execution, though I bet it worked better as a sketch as you see that in three dimensions it loses a bit of structure.
Consider placing the seams in a way that the backpack forms a shape that stands on its own and works together with the flaps as well.
To improve on the space-inspired tech aesthetic you can use ultrasonic welds or adhesives on the seams.
See for example this Patagonia pack:
Still it’s a nice backpack and I am sure it will sell purely for its stylization.
I’m sure everyone here will be very happy if you can tell them where to source that gold coated nylon ripstop.
At Profabrics they have one but it is not nearly as golden as this one - http://www.profabrics.co.uk/products/gold-pigmented-pu-coated-ripstop
You can also consider adding a copper variant - it will look great and more sophisticated with the black plus this look is very trendy at the moment.
