Is the top tube round or oval? It looks disproportionately bulky and I would prefer it to be highly ovalized. Perhaps two tubes, like with the titanium frame, can be used.
Thick tires and top tube make the bike look bulky.
Swift and Origami: the fonts and weights are too different. Keep the font style, size and weight close.
How hard/easy is it to remove the bolt attaching the seat stays to the top tube? Make it secure but easy to remove.
That green is not my favorite and I will wait till I see it in another color.
