Northern Spark: Twins?

I really liked the two women below.  I was certain they were twins. 

Meet Joanna and Sassa!

They are NOT twins.  But, they are sisters.  Joanna is working and Sassa, is four years younger and is still in college.

I liked both photographs and couldn't decide which one was better.  How about a poll?  Any votes?

My sincere thanks to you both.  You were most delightful and charming!
