yo!
looking good, i like the explosion, and its not too firebally, more debris explosion which is cool. The sky seems a little bare, but then there aint much you can put in the sky without lookin ridiculous… lol
a thought, maybe make the reflections of the other buildings but i’m not sure if thats much of a good idea. however i actually like the girl now really, in her unfinished state! lol. it’s like ghost in the shell, but shes not naked here…;p high tech camo suit rendering her partially invisible.
Also, typically i’d like to see it widescreen but as you’ve probably noticed in my thread im a massive fan of cinematic widescreen shots rather than pure illustration so maybe ignore this bit 
Keep it up! I’ll be waitin for the finished product!
