When I look at your progress I have a moments of regret that I abandoned blue sky for more sunset scene ;). I really like where this is going. Details which youv’e added to the skyscraper really makes it look more interesting and I like your new color scheme. As for possibilities of improvements… of course it,s just me, but that almost-black building really drags my attention (as if it would be the most important object), and more distant water seems to be a bit oversturated (in relation to the distance).
Overall - I really enjoy your vision :).
