remember that devil lies in the detail... and so far what I can say... theres no devil here
If You want me to be more precise... in this kind of scene ( and the models ) You cant go BLAST in the modeling / detail... thats for sure. So Im not gonna tell anything about the models
maybe try to improve the materials and the lightning ( add bumps / scratches on those models so they feel used by someone... )
in every shot ( if you aim for realism ) You should always go macro with the depth... ( car is made from little little blocks... not real car scale - but toy scale )
textures are terrible ( in terms of colors and the overall quality ) better remove them and go for one glossy color with little scratches for blocks....
contrast / brightness - I know everyone has different screen setup... but this is way too washed out...
for instance... start with kodakchrome 64CD on gamma 2.2 and play with exposure a little...
and definetly improve the environments
You should definetly go with slight vignete.... almost not visible... but it will darken a corners a liiiiiiiitle bit... and You can focus users attention to the center on some of them. ( not all around )
and set renders to pathtracing at least. We got 2012.
sorry if its been to harsh... but I lack of english skills.
and if this doesnt help for like 10% of quality..... You must watch watch watch watch ... movies / posters / shorts / vfx movies / weather outside / people on the streets .... watch life and the colors
