I really like what you have done here, it's very professional looking to me.
Your composition is REALLY good, your lighting is good, your choice of models is good, the warehouse looks good, so it's ALL good!
I'm not sure if this is your style or not, but to me, the whites are almost blown out, (or, are) and the blacks are almost solid, which shouldn't be. I say that, but if you did it intentionally, that is your style. (And who am I to say?)
One little thing that doesn't bother me, but could add to it 'some'...
The place looks like an old warehouse, but the floor's only slightly dirty. (Or, it's leaves, I can't tell) To me, the floor should be swept up, or about 3 times more 'stuff' in it to give it a more gritty look. Personally, I'd rather see more leaves, or whatever, not a whole lot, but something to 'add to' it, rather than distract our eyes from the main subject.
One more thing, the 'red bag' or whatever it is on the rear fender is kind of distracting, you could de-saturate that yo make it not so noticeable, that's be my only real crit.
Like I said though, I think you did a really nice job on this, and if you left it alone it's still a great job!
