It's okay
Ugh, I don't like the melody, really. It kinda sounds like you went into the step sequencer for FL Keys and just scribbled away. It doesn't really adhere to any key signatures that I know of, and it doesn't sound it, either. You should start from scratch and mess with the keys until you get a melody that sounds euphonic (pleasant to the ear; doesn't hurt to learn new words) and experiment with it to make it sound better. Mess with chords and intervals, too - it's like multiplying notes. Don't be discouraged; music is all about experimentation. It's like you're in a lab with a bunch of chemicals, mixing them together until something cool happens. Not like a cure for cancer, or something to solve world hunger - just something cool. Peace.
