I love entry 264 and is my top choice now. Can we experiment a few things on the logo:
1) Try to make S and E capital. 2) Try to make the ball look more like a sun. The deep color looks fine, but try to get rid of the reflection on the ball. Rather try using some other trick to give it a 3D effect. May be a shadow of the ball on the ground.
Could you also try #264 with no lines inside the ball. Right now it makes it look more like a golf ball. I want it to look as close to the sun as possible.
