certainly not intended that way, but looks kinda toyish dont u think? and please dont kill me for keepin the horizon visible…its sumthin personal 
and natty thanks for the material help, 8)
I think it looks good, Only things i would change is the glass seems too refective too me, real glass always looks a little black, usally becuase there isnt any lights on behind it. Also, maybe change your placement of the sun. Your shadows are all falling behind the building. Change the sun to get some more dramatic shadows.

I agree with comments above.
I also think some of your plants done in post need some variety or rotation. It looks very repetative. I would also add some mullions in the glass or express a butt joint at the glazing. The tree on the left seems a bit cartoony…
Its looking good though.

it reminds me a secesionist building , maybe otto wagner or loos …
by other side if u compare the road size , the car and the maN , they seem to belong different worlds as toys do. 
regards
definetly not loos
