If you did a beach resort, you should do a brochure for it. You could all so make brochure for a concert. If you did a amusement park, you could make a poster. You could also make one for a concert too. And for an island, I feel like it would be normal for a island to be on an ad on like the internet, but if not, a newspaper. But these are just options, you can honestly do anything you want. If you like drawing a lot and putting a lot of details, you could do a comic strip, in my opinion. But you don’t have too.
