the city Wow...
The city is amazing. And you said you used 3DS MAX. To tell the truth, I have no idea how that program works, how it's used, and what it is capable of. I can be pretty sure how much time you spent on it... a lot.
It looks really cool, but I can't write a proper review if I don't know what the program is... But to a normal viewer, or anyone with respect to detail, can see a lot of effort in this. Wonderful job.
