Moss

I've tried all sorts today for Tiny Tuesday, but this blip of moss is the best of an uninspiring lot.  I've blipped nuts, netsuke, spoons and tacks and nothing has seemed to work except this;  I think perhaps it's my mood and it's one of those days when nothing is going to please. 

On another topic, has anyone advice about tiny spots on sensors ?  I have the "clean sensor" option permanently on in the camera, and I've used a blower on it, but this hasn't done the trick.  I have a brush but I'm nervous about using it.

Thank you again to  Nickimags888   for hosting TinyTuesday this month.
