my first logo was rejected, help me please, Give advace ?

The concept isn’t strong enough and the gradient effect and color combination doesn’t work work well. Also you need to create a horizontal version and color variations.

I but before i was create a horizontal and color variations, but doesnt work

Horizontal and colour variations aren’t actually required, as it’s not mentioned in the official GraphicRiver logo requirements. Even taglines are completely optional.

I appreciate it, but I’m no so sure my comment is the answer to your question.

apreciate it, thankyou for your response,
