look good
but why all the air fresheners and cradles on the vents in #1?
steering wheel is cropped in #2, is this by design?
those yellow and black chevrons are distracting in #3, don't look at bad in B&W later on.
the corsa is the background is distracting too
#4 and #6 are my faves
touches on these for me, I would crop out the building door on the right of #4
#6 doesn't look quite horizontal. but that could be my eyes! (it might be looking at the background verticals)
do you have a polarising filter? for the glass? and for the car with the black slicks, I would turn them so the camera can catch them more, and/or hit them with some water mist so that they reflect the light more for #4
in the earlier shot, the wheels are so dark it's almost like the car is floating!.. which is fine (however, if the car has blue neons underneath the sills, I do NOT want to know
)
I'm not a vauxhall fan either but I quite like the look of the astra. not too OTT
good use of DOF with the 50mm too. sorry, that's quite a rant, hope it's received as it's intended
