I like kataray's work.
She has a nice concept of the cycle, which I really liked and the incorporation of love in it improved it a lot.
Adding borders would have helped more, but I like it.
I'm torn because of Blueberry's work though.
Her work has, for me anyway, the most "sprites". I also like her concept as I once slapped myself everyday of using a butt ugly ghost until a very generous cousin of mine quit and gave me a very special aura. Her, oh wait, His sig made me remember what I've been through.
So....
I'll go with both of them.
If I cannot cast a vote for the both of them, then you can consider this post as a null vote.
