Trying to cover the drums up because they aren't very good probably isnt a great idea. I would say track them again if your serious about making it sounds good.
My suggestions would be, a lot more bass, guitars down.
The kick could do with less 'click' and more 'thud'.
If you could bring the mids and lows up on the lead vox, it would possible make the deep screaming phatter.
Got potential, just needs to be tighten up and made a bit thicker

Some of the riffs are nice. Is it recorded to a click?
