Hi there! Here's my submission for you to review. Instead of using a castle, I decided to using the actual jumping castle with cartoony looks, while the boy and girl using a crown and playing in the jumping castle with happy faces. I think this concept will make the audience recognize easily that you are a jumping castle hire business by looking at the logo at first glance, since the use of ordinary castle logo are already overused at logo design and could be interprete as other business. Let me know what you think. Feel free to ask any changes if needed.
