I think so far, the peacock tail felt like it took the longest. I think the reason for it is the constant change of color and having to go over some of the stitches again with Kreinik blending thread. Because I'm looking at my logs and it only took 2 months at about 103 hours, while the border took 177 hours to stitch. But looking at the results now it is well worth it.
Next up is the two trees that are to the left of the peacock.
