Well i think you have a lovely unique way of doing photos no matter what you do . Even if i don't always agree on the concept, the beautiful work you do always makes me stop to admire . It is your choice and no-one else's.
I don't understand why if someone doesn't like your work they bother commenting at all but then again we seem to be sadly living more and more in societies where niceties are going out the window.
I have to say in general i am enlightened by Deviantart as the vast majority of people are so friendly and lovely to know including yourself
I don't think anyone minds constructive criticism done in the right way but for them to be deliberately hurtful towards you just baffles me as you certainly don't deserve criticism such as this.
