I really like your fabric selections - I think they work well together! I wouldn't incorporate the teal; I think the quilt will be more effective if you keep it to primarily orange/green. (I would use the fabric on the left, I just wouldn't add any more primarily-teal fabrics).
My only concern would be with the ribbon. I think it's too close in tone to the other orange fabrics, so it won't stand out enough. Of the fabrics here, I would either use the bright orange (4th from the left), or the green swirl (6th from left) for the ribbon. They stand out a bit more.
