The 5th picture I like the view, nice wheels, the majority of the pics appear a little dull, the colour of the car would make it hard to jump out at you, salt flats or some place white, or the contrasts with your car would make it pop.....
i noticed that also, they exported darker then they where in lightroom, strange. maybe its editing in pro-rgb vs exporting in s-rgb?
it also maybe slightly this new monitor im using, im going to export a new sample, could you tell me if this is a better exposure for your screen, trying to standardize as much as possible.
