@ Tommeh: To blend the logo, you have to decide on what to focus. There, the planet, texts and symbol are all main focus objects. You cannot have that much focus objects in one small composition, all having similar contrasts and colours. You have to decide on where to focus and making that object / layer coming forth.
Think it like the eye looking at an object, the other objects around it become background ,you dont focus on 232372 different objects at the same time.
