I think the Hylian Shield would be awesome. The details on it are really gorgeous and it's definitely a very recognizable item from the series. The others are great ideas as well. I can't wait to see the finished product!
I agree on the Hylian Shield. We seen the Hylian Shield almost in every 3-d zelda game. So probably u know more how to sculpt the Hylian Shield. And it's probably hard to sculpt so maybe this will get u to a starting place
