I like the second red (lighter) one. The green does tie in with your others, but I don't think it flows with the darker brown. The other blocks where you have green, have both dark and light shades so they blend. Just my opinion.....that said, ALL of your blocks look great! These blocks all together are going to make a very interesting quilt for everyone.
But you might want to wait and see, maybe you will want a spot of green at some point.
