Thanks for the suggestions so far. This is the 3rd revision, and after EQ-ing the drums and working the volume levels, I believe I have a roughly finished product. If you have any more suggestions, please leave them below or PM me. Again, I appreciate all the advice so far.
The main guitar riff is one I came up with about 5-6 years ago, and only recently was I able to turn it onto a full song. The influence was to make a video game boss battle theme.
