Looks like you really pulled it off. I was expecting to see the smaller Nova taillights to drive home the Nomaro theme. Those Ventura taillights do look a bit big, but that rear billet panel really makes it look nice. Seats look great as does the engine.
As has been said, it's pretty trippy. Crazy as it is that 3/4 view photo makes me think of a Maverick in a weird sort of way. Coolest thing about doing this helps us visualize "what if GM designed ..."
How much suspension drop will it have? I'd like to do a quick photoshop when I get a break in the next day or two, I can't wait to see it lowered a bit. 
If you haven't already bought it all, while you're shopping around for suspension, give us a look...
