Photo stock

I attend some photo stock site. Some of them are the following:

• Fotolia (IT)
• Dreamstime
• 123rf.com

My goal is to make known my work and exchange views with those who see it.
I think it is the only way to grow. Clearly with these sales systems do not have opinions andcomments, but from what I understand sales speiciale interested in this field.

Please leave any kind of comment regarding my work. You offend me if you do not like the job. More straightforward are the better.
