The track is overpowering your vocals! I want to hear you sing! From what I can hear, it sounds like your delay may be too early and it's creating some feedback with the main vocal. If the original song has a fast delay, I would recommend adding a chain compression to the delay so that you only hear it when you stop singing. This will eliminate a lot of the feedback. A really cool trick to thicken vocals is to use a stereo spread! It basically pushed the auto out to the sides and it gives you a deeper sound, so when people listen with headphones they feel like the audio is coming from around them. All and all it's a really nice track! Gusto ko!
