This is Circus Themed annual school event, so my logo is combination of a circus/festival style logo with the elements of science/inovation.
I incorporate science elements sucah as rockets, molecule, sparks, light bulb, and test tube. I make the tent from the rocket smoke. So it blend well with the logo and also add a fireworks effect.
The ball and the knight symbolize Sports.
The tube and fireworks symbolize science.
The bulb and the rocket symbolize innovation.
I put the tagline on a banner under the main text. This banner will make the tagline blend in with the whole logo. Because banner are very related with circus and carnival.
