I'm with Mj & Christina (your logo is so fun!). Why wouldn't you want them to laugh? Life is serious enough.
I say this as a person with a
logo that is absolutely ridiculous. Really. But people smile when they see my logo and they think of tasty ice cream.
Your logo sets the tone for the client's perception or your business. If you can make them smile they will look forward to getting to know you.
Good luck!
