The holo combined with the color shift is really amazing. I love the red/orange/gold/green pigment, and it is really noticeable in this polish - much more noticeable in person than on the internet. I haven't tried using it as a topper yet. I worry it will be a little too dense, but it is worth a shot!
I found it to be a great color for the fall and holiday season; I think I am going to purchase Rosewater as a spring/summer version :)
