Not bad, but they could use some work.
It seems that the background is a but too bright, it appears to be blown out...or at least the histogram is piled up on the right side. This is probably caused a loss of contrast in some parts of the bike...like the mirrors and handlebar etc.
The reflection of the lights are causing highlights all over the bike...but that's almost impossible to avoid on something like this.
I'd like to see it with more fill light. The dark parts of the bike that aren't being lit by the overhead lights, are too dark and seem to be loosing detail.
There seems to be a bit of a blue/cool color cast, the 2nd one more than the first. I'm not on a calibrated monitor right now though.
I guess that if you are setting up a booth to do a lot of bikes in succession...then there will have to be compromises. You could probably spend all day trying to perfect the lighting for just one shot...but that's not going to be practical is it?
