Before and after coldworking

Would anyone be willing to post before and after pics of a casting that has been coldworked? Especially one that has lots of fine detail? I would love to see the difference/progression. I have seen plenty of 'after' pics, but very few 'before'. Even a 'just out of the mold' pic would be great.
Cheers in advance.

Hi Jenna,
Although Im not directly answering your question, I don't cold work my casting at all.
There's no need.
Here's a high res photo.

The only cold working I do is use a toothbrush with white toothpaste (not gel toothpaste) to brush away any residue investment stuck to the glass (white toothpaste has ultrafine abrasives while gel toothpaste does not. Dont brush your teeth with white toothpaste!).
I also pre-fire my mould to 650C. That always gives me a clear casting
