Yay for crow temple!
I love the crow temple theme, and yeah, sadly there aren't too many of them out there. This is awesome! Your design is very solid. I'd swing that hammer around like nobody's business! One thing though, and maybe this is just something that's solved once it gets into 3d. But at first read, it appeared as an axe rather than a hammer. I think it's because the bottom tips of the wings give it a sharper silhouette. Again, it could be something that's easily solved when you're able to view the thickness in 3d. I love this design though, very bold features. This thing will pop in 3d, can't wait! Well done!
