A sort of mono Abstract Thursday

Today's effort began life as a bunch of decorative acorns (getting ready for the dining room Christmas tree) on a brightly coloured toiletries box.  My picture was given a quick spin in Photospiralysis and then, because I saw that the theme was 'mono', I turned the image first to black and white and then gave it a yellow tint.
Many thanks to Ingeborg for continuing to host this challenge.
