I think it looks great. The major problem with most 3rd party cases I've noticed is that they cause major drag. To be light weight people drill holes in them and that causes even more drag. I managed to totally over breath an inspiration fighting to get to a line in a current, whilst using a metal box of drag.
So well done in making something that does what you want it to do whilst being light weight weight and not causing more problems than it solves!

Bet you, that you could sell a fair number of them to if you wanted.
