Friendship Scheme Logo Ideas

I felt it was important that the "friendship" scheme had an identity, so as to give it the true feeling of being part of a club. I decided on the name "Yorkshire Sculpture Park Family Friends".
Looking at other significant galleries logos, what was obvious was the use of openly planned, plain type logos .
After A few experiments with layout, text and phrasing, I settled on the logo in the top right as this best reflected the Yorkshire Sculpture Parks current logo but stood out in it's own right. The idea second from the bottom, on the right column was also taken in to consideration for it's in-keeping design (using the circle form) but also being significantly different from the parks current logo.
Each of the galleries logos was taken from their respective websites:
