Love the idea Griangraf, and your composition is absolutely spot on. The only issue I have with this silhouette is that all the edges are blurred and slightly out of focus as though you were using continuous autofocus instead of locking focus on your main subject. Otherwise it’s a terrific image.
I agree with the sharpness/ghosting issue. It mostly due to the long exposure (1.3 secs). It was taken with a 350D and a Sigma 50-500mm (good lens but not were fast). I have put the image into PS and sharpened it. I don’t know if makes any differnce. See below.
