First one looks really good
Second looks okay but very samey, if there are street lamps then really there needs to be a street, not just a floor with the same texture as the wall
Thirds looks okay as well - but very limited. The FOV looks a bit off and the wall textures look very samey. Really if that's the best outdoor levels can get then it's worth sticking indoors. For me, I'd like to be able to have streets and pavements etc. (and I suppose I can if I model them).
Sorry for being critical, but somebody's got to do it
