There’s the siddur opened with the tefillah / song, that is going up to shamayim with malachim singing and bringing it up with song, because just like the words say - happiness helps the tefillah have greatest impact.
The malachim are kept abstract on purpose. Not to distract from the siddur. And because I felt it more appropriate. But they are pearl white - and pop off the canvas. So it’s very much seen and understood.
There’s dark on the edge because this is the light in the darkness. Which can all switch in a moment and this is the reminder.
