"good Old Henry" - Cardinal painting

I was commissioned to paint another cardinal (my most requested bird to paint).  This time I decided to take a different approach.  I spend a lot of time working on birds with very bright backgrounds of white, blue, green, yellow, etc.  This time I wanted to change the feeling by going with a background that is much darker.  The background might perhaps be the side of a house/shed, or maybe it is getting dark outside.  Who knows?  The goal was to change up the look and the feeling, and I believe I accomplished my goal.

What are your thoughts?  Should I do more dark background birds?

BTW - the name "Henry" is a nod to the grandfather of the person who commissioned this painting from me.
