|Greetings from the Critique Club!
First impression: Love the bokeh and the details here.
Artistic: This is great use of shallow dof, and the red definitely pops without being too much. The only thing I'm personally not fond of is the pedal showing at the bottom; the pedal arm (or whatever it's called :-) just intrudes a little too much, especially as it's light in colour.
Technical: Apart from the minor nitpick with the bottom pedal, there's not much else to find fault with. Composition is simple, the ambient lighting adds a nice feel to the shot and the details of the locking mechanism are perfectly rendered. The swirly blue/green bg adds a slightly surreal edge, almost a zoomblur or lensbaby effect.
Overall: Gave you a 7 during voting and glad I did, but if it were possible to have shot it without that crank arm and pedal lower or out of frame, may have got you an 8.
