sheesh Adam, that second last one is da bomb. He has to be happy with that, perfect compo - the only issue I can see is the front whell looks distorted, possibly two steps back and a slightly longer focal length may have helped here?
lighting is on the money, nothing to suggest here, i assume two lights with one softbox?
The pose on 3 is good, however did you try some other combos, ie, right hand on knee etc, i am cluching at straws to find somethign wrong with that one

The last one is good, not as good as the 3rd, this is mainly due to the flat nature of the composition, however your hair/back light does help make the bike and dude pop from teh BG.
The first two light painted ones are up to your usual high standard, if I ever do a bike, I will know who to ask for tips

I would like to see a 3/4 compo on the first image style.
Not a bad bike either..if your into that kinda thing
