The "depth" problem is your alternative images are perhaps out of the depth of some viewers...so that is always with art.  I believe universal acceptance would render your wonderful alternative shots as less valuable and would require more mundane subjects. 

You don't want to do that, certainly!   Stick with what you do and do well, come or not the comments.   That is my 2cts.           TomDart.

I am not very familiar with other or better photography sites overall and have no recommendations in that regard.
