Vinka,
I agree with Angelina. "Views don't equal sales." I, too, have had thousands of views on many of my images, even over 30,000 on a bluebird image that went viral on Stumble Upon several years ago... and that one and others have not sold.
Many of the views recorded here on FAA are from bots and other members of FAA, not necessarily buyers. Alot of competition these days, so you need alot of patience. And, you need to market your work elsewhere on the internet to bring buyers in.
Best of luck to you on your sales!
