Blue on Blue

Have been fascinated by the new weekly challenge from Markus but didn't think l would have the skills to take part.
But this week it's using a simple DIY filter so l thought ld have a go.
Used one of the new tumblers l blipped two days ago as my filter.
Just loved what came out of the camera, just needed a bit of cropping.
Thank you Markus!
Also continues with the colour challenge set by hobbs.
