Cutting brass sheets: replicating Christmas ornaments

I'm looking to replicate a brass ornament for a dear friend. The ornaments in question are similar to these (http://imgur.com/a/WGPXE) Do you guys have any suggestions on how to get the precision for the concentric rings as well as the detail inside?

I thought about using a Dremel for the detail work, and snips for the outside, but I'm having trouble coming up with a solution for the rounded rectangles. 

Thanks!

A jewelers saw would be useful for this. Fine metal work also makes use of punches, dies, and specialty tools like a "dapping block," etc. A good old "nibbling" tool might be handy also.

I have a nice burly antique punch (Whitney No. 5) that pops out holes in sheet metal like butter. They probably make smaller versions, as well as shaped punches.

Most modern examples of this work are probably laser cut, though.

mount the brass piece on a thin piece of wood and feed it into a scroll saw or coping saw. The holes you would have to drill out and shape with a file.
