The first one looks pretty great. I kinda hate the second one.
I think you guys are crazy! That second one looks phenomenal, especially the building on the right with casement windows and a bit of streamline Art Deco style. That's the kind of bold architecture we need to make the Arts District have an even more unique flavor. That first photo looks about like any other downtown development anywhere in the country. Nice, but nothing memorable.
My favorite parts of OKC's downtown/midtown are in areas which have a bit of mid-century modern flair in the buildings, and that second design is a bit reminiscent of some of those. But it is probably the more expensive option and probably won't be built.
