|Greetings from the Criticque Club!
Initial impression: As mentioned in my earlier comment, I love these old trains and I like the sepia. I find this shot to be very atmospheric and evocative of the time that these trains ran the rails.
Technical: I like the composition here as it helps show off the immensity and solidity of the engine. Good dof and I am a fan of this kind of pov. Looks like it was shot on a slightly overcast day as there aren't any telltale areas of glare on the metal. Light in upper left borders on being flat, but isn't, so good that there is a softness there to contrast with the engine.
Artistic: Very good choice of pof, but the crop is a bit tight. I'd like to see more room in front of the train, so there is a sense of a place for it to go. Also, would like to see either the top of the cab, or all of the wheels, just to further enhance the scale.
The pp is quite pleasing, and very clever idea to use the sepia tint to help hide the Christmas lights! One trick I learned here on dpc is to do all your image adjustment work first, then resize, usm, and save for web.
All in all, still very much one of my favourite shots from that challenge, and I am glad I got the chance to criticque it.
Feel free to PM me any questions you may have.
