i think its crap...
well heres my reason..
first of all... you gotta decide on whether or not you want it to be realistic or abstract
in this case where u wanna show things like silence within the city.. i guess it would be better to make it more abstract...
yea the moving blurry lights and things sort of show movement but i dont think its enough... u want to be able to speak through your drawings/renderings... where when one sees the picture he can tell immediately what is your main concept, whats ure focus.
at the moment... it doesnt really show anything... what makes ure building different from the buildings around it? whats the relation?

what you should do is try to make the drawings then go around and ask ppl what they think the picture is trying to convey
or you can even just do a blind crit with your family members for practice

im not saying that your works are bad... dont just focus on making beautiful renderings... write down ure concept in one sentence.. put it in front of your computer...then think. How can i show my building as the constant? how can i show movement? how can i show "cramped"? what do i want teh users to feel when they see my building?

i hope u dont take this in bad... just trying to help

btw
the model is good and i really like the building.. especially from the 1copy.jpg picture..and the facade looks really nice from that angle
