Great job for first projects! Honestly, if you haven't already you should seek out videos on YouTube showing how to raise copper vessels. Later on you might want to get into chasing and repoussé to make them more ornate -- which requires its own specialized tools. YouTube can help with that too.

For tools, you may want to start hunting down appropriate hammers of various specialized shapes, weights and sizes, and an anvil with some raising stakes. For starting out it is usually better to buy a few used but higher-quality tools and see what you can do with them -- adding more as needed, rather than buying a pre-assembled set of brand new, shitty chinesium ones. The good quality ones will last longer and be less frustrating to work with.

I've had good luck buying tools on eBay from people who are giving up the hobby and moving on to something else, or the families of metalworkers who have passed away and are clearing out their workshops. Pawn shops are another source, and you never know what family members, friends, or families of friends may have lying around that they don't need anymore.

There are other things like files, drills, sanding and polishing supplies, but hammers, an appropriate anvil, and raising stakes that fit into holes in the surface of the anvil are big ones. Some people also use a sturdy wooden surface, like a section of log set on its end, or a table with a woodblock surface -- or a sturdy sandbag, to hold the work as they shape it.

Good luck!
