You won’t offend me
and too be honest I am not the knowledgeable about all this.
I really do like the lighting and feel of the image,
Nothing is wrong as it is your image to do what you want…. I just felt it lacked impact as all the empty space around your main subject detracts from the main subject. There is more to composition than rules too, like Dof can be a great composition tool.
I did a quick mock up of DOF in photoshop to show what I mean and did a couple of crops, hope you don’t mind.
My intent is not from showing off but from what I see as a viewer and in the spirit of helping out.
