Banner design for the playing area

We need a graphic designer. For children’s play area, a banner measuring 4.1 m in length and 1.2 m in height should be developed. The banner will be placed on the front of the administrator's desk. The counter is clearly visible to visitors from the entrance, so it is necessary to make it attractive for children. My wishes - the color combination should be juicy and "tasty", it is desirable to use images of modern cartoon characters, but if you have more interesting ideas, then show. The name of our play area is Fun Production, and I will send the style writing later to the performer.
