Search Venice and you get 19,946 images. I to have my own version of your picture in my portfolio, this has only 4 sales. My best advice is this, according to your profile you live in Moscow, search the best selling images of Moscow and get out there and shoot some with your own style added. Not mid day touristy shots that cruise visitors like myself take but evening/sunset/nights shots. Good luck and get out there :-)
I think after four months on the site, reading the blogs, looking at other people's portfolios, looking at the top selling photos you'd know that having a larger portfolio is the answer. Most contributors don't start seeing sales until they have 100 images up. I've been posting 100 a month. Some serious contributors post 100 a day! What are you expecting from 12 images? To retire? Get busy, stop thinking that posting a blog with tags such as "useful" and "sex" is going to jump you to the head of the line. Do the work.
The importance of a larger collection is definitively a priority. Your collection, though small is very good. Diversify your subject, but always remember quality is the upmost importance. Good luck on your future sales. A great example I can offer you is ... Though i love to capture landscape images, I took a photograph of a cup of coffee, and within several days, a sale occurred.
If only it would be that easy to get sales… 12 images is not enough to expect sales very soon. You should upload more images especially if you only have buildings and landscapes you need hundreds to get some decent sales. Your images are usable for travel brochures or websites but you have allot of competition so you will not get far with only 12 images. Try to shoot more commercial, people and concept images. Isolated objects also seem to sell well but my best selling images are people. Try some searches for subjects you like to shoot and then see what sells and try to compete with that. But most of all... get more images online! My portfolio is very diverse and daily sales started for me at 150 images. Good luck! :)
Max, usualy it takes months for the picture to find a customer. Do not worry, it will come. In the meantime keep uploading. There are milions of pictures on line, so yours 12 need more brothers to fight for customer.
