This is a really beautiful bust. The casting is well done, the details are clean and sharp, and the overall nice weight and the quality feels solid and well-made. The size is exactly what I expected and it has a great presence once it’s displayed. It looks elegant and adds a nice artistic touch to the space. I’m very happy with how it turned out and would absolutely recommend it if you’re looking for a decorative statement piece.

Very nice size I spray painted to get the color I wanted came out beautiful. It’s a light weight. It dropped and cracked open but I will use super glue to hold it together. Still looks nice just weathered. It could’ve cost less.
