I think I'd have cropped a little more harshly top and left - the wall up there is negative space. What with that being an important part of the composition, it's a bit hard to tell. I'm giving it ten anyway.
Its interesting shot...simple colors and simple lines... still somehow i miss real point of interest. If you could get someone to pose you on bottom at white wall with spread arms would add some extra juice to it.
Great perspective. Love the zig zag of the stairs, the rectangles of the glass panels and that "little" human in the bottom left. I think I might work on the contrast a smidge, but the composition and everything else is good. 7
