You're 17 and I know you don't which is why you aren't a real designer. You can claim you are though. A real designer can take feedback and articulate a response to the feedback given. Your designs are bland, inconsistent and have no equity to them. You probably don't even follow a design process.
Despite the blunt nature of his response, I believe it's better to to listen to every comment seriously and from as much people as possible. Don't rule out someone's opinion because he is unprofessional or he says it in an unpleasant manner. And as for me, I look at this logo and find it cute, but if I look at it more than a second it's hard to understand what is the strange polygonal shape inside the "shield"
well, it wont surprise you that the outcome is really convincing ! looks pro the lighting effects are sophisticated yet discreet the colour scheme is really pleasant overall, a well perform piece of art !
