Transparent obliteration

First I tried white thread with straight lines, but I didn't like it and took it out. It was somewhat shiny and attracted my eye. Now I am trying grey stitching in curvy lines. Trying to 'transparently' obliterate the 'less important areas' so that the encircled areas stand out more. But I think the stitching creates too much pattern and competes with the area that I want to stand out. But I like it from farther away... where the pattern is less dominate. So I continue anyway seeing where it leads. Sometimes trying is all you can do.
