Logo creation for long sleeve button down - repost

My partner and I are working on creating a long sleeve button down dress shirt targeted that has a unique seahorse logo with a personality. Since we are in the beginning stages of product creation, we are sampling a few logos to see what logo would look best on the dress shirt. There is a manufacturer willing to cut and sew the shirt but the marketing is whats going to sell the product. Below you will find the requirements for this project 1. Produce 10 creative seahorse design logos with simple colors on a single document using professional design tools. 2. Make sure the logo will be scalable to a dress shirt on the front pocket.
