, I've taken a gamble in hoping that you wouldn't mind my editing your images. Below is an amalgamation of your two with a re-crop (to pull it towards behaving like thirds), showing a 3rd way.
It's a very quick job with layers, and then reimagining a faux Y-lighting set-up. I'm not entirely happy with my edit, but hopefully it illustrates another path that you might wish to pursue. Personally I'd prepare the image this way before any tone mapping.
Given your original images, let me be the first to say that I prefer the 2nd one, but more so if you didn't tone map it (hence the "odd colours" that Burun
described). The context saves the image from being dull, which the silhouette excludes and results in no foreground interest or real context.
I'm sure the others have their reasons for liking the silhouette, but I don't because of this lack of context and the overall boredom of subject.
Thanks for sharing.
