Well, in object head, you can try a main item from a favorite activity you do, or get examples from object head shows like "BFDI" on Youtube, and put ur own style onto that with ur own ideas. Other OC wise, try making a example of yourself, or a mascot the represent yourself/real life figure. If that is not what you are looking for, try adding un realistic things to your mascot, like cat ears, ect. Animals, try being creative and adding personal touches to it, maybe based off of a pet or other animals, and have a fun color pallet that you think suits you. If non of my ideas fit, try going to an OC trade and trading or looking for ideas.
