Also tweaked some other SEO factors, like the image titles, the blog title, leaving out the deviantart sharing code and so forth. But most of all I think the difference will be whether the image is hosted at deviantart or at picasa (blogger's default).
[Update 23 January 2012: four months went by, exactly as expected both pictures are now in the top 10 when image-searching for Winamp Green. SEO is not so difficult after all - one just has to understand a few main principles. Number one to me?? ...post your content on sites that are owned by google like youtube, blogger, picasa. Keep your content clean and authentic.]
btw: Winamp Green Modern is still the color scheme I use all and every days :-)
