Help - How to get a good finish

[CerriSian]

Hi

I'm very new to this hobby and am really keen to learn. I have only finished 2 pieces that I'm happy with. (Attached) I love both of these pieces from a distance but the photos really show up the scratches and and marks in the silver. I guess working a lot cleaner will hopefully come with experience but I would like to learn more about how to get the best finish as possible on a piece. I'm on a small budget so I'm restricted to hand tools and a rotary tool. Any advice, top tips or video recommendations would be appreciated. Both of these are a mixture of silver clay and silver wire (Not sure if that makes a difference )

Thanks
Cerri
