‘Visionary’ unfinished

Asking some help from you.–I really can’t decide whether a blue-black or brown-black background would add to the bright feeling I wanted in this portrait–or not!
What would you say?
A. Leave it as is.
B. Give it a blue-black back.
C. Give it a brown-black back.
D. Other input?

Thanks for reading about my dilemma!
