Rococo is an art style and is usually as all styles changing .Be familiar with basic terms , spend time at museums and in libraries. If you are working with a specific customer talk to him and find out what he wants .You don't have to stick blindly to a style.
Firearms engraving can be many different styles. The very fine Italian Bulino,
to small scroll, large scroll etc. you may be given a photo of the hunter's favorite hunting dog to engrave . Take a notepad with you always and sketch and sketch !! To engrave an animal you need knowledge of anatomy .Butcher a deer and learn their structure .I've seen to many examples where the 'artist' knew nothing about the animal. Challenge ? Make sketches of a deer walking away from you but turning his head and neck to look behind himself !
