I don't see a lot of usefulness in those flower based black and white designs.  Expand a bit.

'Something' happened in September 2012 which somehow affected files uploaded from that month to now. This has been admitted by admin. Many/most of those who report are finding that files uploaded after then are much less likely to get credit sales than those before that.
Also for a long time there was the 'curse of the download', which meant that once a file got its first download it went to very nearly the bottom of that search, often to die evermore, but it could rise again once it got to 9 (or was it ten?) dls.

really great thanks for your help and for your time ... what can i do for this issue? i though sometime to invest money in promote my portfolio but im afraid this will be waste of money.

Your flowers of similar design makes up 50% of the images and your cars/motorcycles of similar design makes up 30%.

You just don't have much variety in your portfolio and you're targeting a small niche. There are many variables to a good portfolio gains high visibility. Style, variety, uniqueness, keywording, commercial value all contributes to that. Your portfolio is lacking in many of those areas.

Also keep in mind that 123 doesn't generate that many downloads compared to other sites. Look at the table on the right; it's a good reflections of the market.
