Backside of a t-shirt for marketing of an ice cream shop

C'est ce qu'une entreprise en/au(x) Poland recherchait pour leur t-shirt design

We need a nice backside of a t-shirt for our brand Shark Ice Cream. We are going to serve ice cream, and we need to design a back side of a t-shirt/jacket/top to inform customers where are we located. We would like there to be a logo (attached) and informations about location (Sopot, ul. Monte Cassino 60) together with words "zapraszamy" and "come & enjoy".
We created some ideas on our own, but we do not like it, and it does not look professional. So these attached projects are just our unprofessional trials. Please make it look amazing. You can try to improve these ideas but we are more open to new ideas. Voir plus
