This is really a WIP. The main issue I have is with the volume. I just don’t know why most of mixes are too soft. Any feedback for this will be helpful.

Other than level mixing, compression can have a large impact on loudness. Besides a few Renoise native compressors divided over different tracks, putting a maximizer on the master out will already up the perceived gain. Fiddle around with the presets if you’re not familiar with the parameter settings yet. Didn’t mind the ‘softness’ in your wip btw, maybe some eq’ing and a multiband compressor on top of the rendered song .wav and you’re done.
