I came about this page because I am looking for this kind of angels myself. There are many variations to this particular kind, lots of beautiful photos online. In my lengthy search, I could not find a pattern to them. However, I did find some info about these angels. Dont know if this will help in any way, but I will just leave this right here in case. I found a Russian website, handmade-paradise.ru
According to this site, the artists name is Renegade and she sells these finished angels on fler.cz
On the Russian page I found, there are many beautiful photos of these truly lovely angels! This is what youre looking for, even background on photos is exactly the same. Sorry I cannot help to find the actual pattern (if it even exists), but I hope this can help at least in any way.
