Nice.
The colour scheme reminded me of this :
I like the simple tube-in-tube design.
But won't the overall weight kill you on uphill stretches ?
If you ever reskin it, ZoteFoam may be an option - definitely lighter.
Couple suggestions :
- streamlined fairing aft of your head ;
unless you have a dimpled head or dimpled ball shaped helmet
- does it really need the extra rear attachment tubes ?
maybe the top tubes could serve double duty as attachment (making the structure more like the first pic),
and you can shave off a few pounds by deleting the tubes that run up to the seat
