I really like the tranquility of this design. Office suites feel work-like and tedious.
This was a nice little visit to a mental pond with lilies before the program starts.
If they move and flow a bit, it would be even more organic. I suppose they could appear and fade in some sort of natural arrangement.
If one of the leafs align with the cut of the page (which btw has a pixelfault out to the right on the dogear)
and maybe shares the aspect of edges being equally long to something found in the icon, then it ties together.
Pond, existing colour, lily, herbarium, icon.
