Help with designing a chapter icon?

[Biotic Khajiit]

Ive decided that after my necron army that I would want to make blood angel successor chapter using lots of forge world gear, anyway Ive come up with a name for my chapter (Angels of Evisceration) as well as a colour scheme (dark red since Im a bit lazy)

But Im having trouble designing a chapter icon for them so if you guys have any idea's it would be helpful.
