The composition is very good, and original. The colors are very muted and for this photo perfect. he overuse of neat image has removed most of the fine details, which I would have like to see.
Beautiful movement and focus going on here; I love the time of day you took this; one criticism is that the "pipeline" has an uber metallic look to it that is distracting.
Hmmm, I like the subject and the colors, but i think it would have looked better if it didn't feel so "dead-on" for the shot. the rule of thirds would really help this one out
