Isn't his point that your statement isn't as well-written as it might be? The grammar of that "pristine in nature:" sentence is shaky, mainly because your choice of a colon rather than a comma results in your confusing inward sensations, and also grandeur, with aspects of pristine nature.
If you're going to write such stuff, you've got to be prepared for people trying to make sense of it. Thankfully yours isn't too pretentious, and the grammar is easily straightened out, but "my artist statement is my own words that are used to describe my own photography" makes one conclude that your photography is confused - which, looking at the pictures, it certainly isn't.
