- Nature is undermined in both. In BNW its through the harsh description of nature and in BR u can immediately see the pollution, smog etc
- BR portrays a scary scene, similar to hell whereas BNW exhibits a world which is not scary, but rather it is cold, mechanical, alienating etc
- BR uses imagery to convey meanings eg: eye is the window to the soul, dominant ziggurat shape of Tyrell building etc as does BNW eg: sun is seen as a ''harsh thin light'', suggesting a lack of understanding of nature
- BNW is more scientific and technological whereas BR is more sci-fi, futuristic. This is immediately evident.
- In BR, we get a warning and are expecting this scene (ie. the scrolled text at the beginning) whereas in BNW we recieve no warning (unless you've read the foreword)
Thats all I can think of atm.
