Transfer copyright to the Client

nice to meet you. My name is Yoshida from B&B Co., Ltd. We are engaged in the retail and production of character apparel and goods. This time, I will make a T-shirt with the theme of sea monsters and sharks. As for the subject of the illustration, there are 2 types of sharks, a whale shark and a cat shark, for a total of 2 pieces. I would like to request that the whale shark be realistic and cool, and the cat shark be cute. * Since there is no clear composition request, is it possible to make a proposal? The main illustration will be the front or back. If you have any suggestions, I would like to consider one point such as the chest and neck. * We also hope to purchase the copyright. Although it is simple, we have attached a document summarizing the requirements, so please check it first. Thank you very much.
