Not sure what to make of it...it's very pretty and looks well-built so you're thinking flagship. But then the internals are decidedly middle-of-the road in spec terms (full HD screen, SoC is a budget part).
The price is in the lower end flagship range so maybe about right if you're happy to pay that for the design elements...I wouldn't personally.
The battery looks under-specced for that hardware - I doubt you'd get more than two-thirds of a day out of it. Unless Marshmallow has brought some serious power optimisations into play.
