Logo submission rejected

Hey guys,

After listening to some of the cool logo idents on the site I thought I’d try my hand at it - I’ve done stingers for radio before but not quite the same as this.

Rather than getting super invested I went for something simple to feel out whats involved. I got rejected based on quality - that’s ok, kinda saw it coming - but I’d like to dig in a bit deeper and understand how I could make this better suited. Would anyone be able to weigh in?
