I love the choice of background in this one. I have a real soft spot for silhouettes and I think the idea behind placing her in front of those colours and textures is superb.
Definitely a load of potential there, but for me it would have been vastly improved with a more interesting pose.
IMO silhouettes of people generally work far better in profile so that there's a suggestion of a face. I tend to think that straight on (especially if the subject has long or curly hair) you just end up with a bit of a shapeless mass where the head should be.
It would have been nice to see her doing something a bit more dynamic and interesting with her arms and hands too. Maybe persuading her to remove her gloves so that you had more definition in her hands?
With silhouettes you're completely dependent on pose and body language to convey the emotion or mood of the image and in the current pose I'm just not feeling anything.
Was this shot taken somewhere local to you?
I'd love to see you go back when you have your new camera (
) and give this another go, because the concept is great and I think there's a lovely image to be had there with a bit more planning and work.
