To create a custom mini caricature sculpture, start with a concept. Then, gather your tools - maybe some sculpting knives and wire for support. Build the basic shape slowly and add details like facial expressions and unique features to make it stand out.
First, you need to have a clear idea of the character or theme you want to caricature. Then, start sketching the basic outline and features. After that, add details and colors to make it look lively.
