When cutting designs from sheet metal, you have a few options. If the sheet metal is relatively thin and you only need one or two pieces, drawing your pattern with a paint pen and then gradually cutting by hand with tin snips may be practical. This approach can take a bit of time and practice, but the cost of the tools required is minimal. If you need a lot of the same piece, a professional shop can create a punch which will allow many of the same pieces to be stamped out using pressure.
For extremely detailed work or industrial production with thick metal up to an inch or two thick, the cutting is often done with plasma these days. This requires that the metal be conductive since an electrical arc needs to be formed to do the cutting. This can either be done by hand, or the design can be input on a computer and then cut out with a computer controlled cutter. This is probably the best way to get extremely detailed designs cut out of thick metal which would be very difficult to produce with more conventional machinery. Make sure that your workpieces are cool before touching them after being cut with plasma. Plasma works very well because it doesn't add a lot of heat to the workpiece, has a very fine cut, and won't warp workpieces. One of these approaches should be sufficient to cut out nearly any type of design from any thickness of metal that you could need for personal or professional projects.
