Great set of visuals but there is something weird going on with your vertical lines in the first image. Straighten those up and it will look much better.How did you achieve the white natural lighting on the 4th image?
Really really nice !Is the background on 2nd image a HDRI or regular backplate ?Only criticism are vertical lines on the 1st image not being vertical ;) and that spotlights cast light yet are turned off. Apart from that really nice images !
