I like your quilt very much! In answer to your question, I like the lighter triangles around the edges best. Many of us (most) have UFO's hiding somewhere ! LOL! But, really, the quilt you are making is VERY pretty!!
Another thing I might change is the 4 brown squares. I think that I'd put them in the 4 corners to distribute that color more evenly.
Other than that, I really like it & think it deserves to be finished.:)
