for Art Span exhbition

I need to choose which painting to bring to the ArtSpan exhibition at SomArts- the size limitation is 20 in X 20 in. Mine are 16 X 20in.
I like both but the darker one seems to catch the eye and i need that to happen in a large exhibition space. So i think i am taking the left one.

I built a 4ft X 6 ft canvas, so now the slow process of gessoing the canvas begins. I want to do one more painting before Open Studios (Oct 27, 28) which would make 10 paintings), have slides made and send them off to SFMOMA rental gallery.
