Whell gat there are just a few things to say, altough i have been aware of this project i didnt expect it to come out-of-the-blue so suddenly. As you can read the people are going crazy again over your 3d-vectorness-city and most senior members point out some pointers :P whell i can say nothing more then they allready did :P
The characters are good vectored altough they seem not of the quality of the background, maybe next time grab a 3d-motoko-scan and extractvector that to give it a more matching vibe. for these vectors i would make them maybe a bit more slightly darker. The backbground is the eye catcher of this wall, maybe a line/text could have gone on that edge/wall there standing infront of.
next time why not try sompt 3d motoko like and a dark night city background ;) look at me giving out ideas altough my walls have been of bad quality ore not even reaching ap at all. aahwhell awesome wall +fav and +creds by me :P
