Nature tshirts for state park

I'm looking for an illustrative design for a series of custom nature t-shirts to be sold in a state park. The design should be printed on a high quality cotton fabric, using a screen printing technique for a durable finish. The design should be inspired by the stunning natural beauty of the park itself and should reflect the importance of nature to visitors and locals alike. It should be a memorable design that grabs the attention of anyone who sees it, ensuring it stands out from other nature-inspired apparel. The chosen designer should be creative and detail-oriented, with a portfolio that showcases prior work. Experience in designing apparel is a plus!
