Kia Ora Just having a quick look Didn't comment on triangles, but for my 2c I would have rated this 8/9 . I would like a little more detail in the hands, as beig a lot lighter than the eye it tend to draw the eye . its a difficult exposure ask but experement with bounce flasha bit. I am surprised that it didnt rate higher as it is agood shot .
Highlights on the hands are a little harsh. Maybe a bit too contrasty. Love the concept and composition. I think the choice of B&W is superb for this photo.
